San Rafael Investment Property Loans and the Down Payment They Require
San Rafael is the Marin county seat, and it rents to more than commuters. The county's administrative core, the downtown professional offices and the flats around the Canal keep a renter base in place year round, in older buildings that were never priced for a spreadsheet. The median home value is $1,298,041 and the median rent is $3,182, a 2.94% gross yield and a 0.38 DSCR at 20% down. At the median, a DSCR loan does not carry this purchase.

San Rafael is a county seat with a rental base of its own
Most of Marin is a place people commute from, and San Rafael is the exception. It holds the county's courts, offices and professional practices, and those functions put renters downtown on a schedule that has nothing to do with whether the freeway is moving. Add the service and medical work that follows a county seat and the city has a rental population that renews itself rather than draining north every time a lease ends. That is the demand side, and it is durable.
The supply side is where the trouble starts. A $1,298,041 median averages three different properties: the hillside house with a view, the older fourplex on a flat street near downtown, and the condo by the Canal. Each has its own rent roll, maintenance profile and lender. A single median describes all three badly, and a buyer who underwrites the median rather than the building misjudges the file before escrow opens.
Age matters as much as address. Much of the rental stock was built before the current code cycle, so the wiring, the sewer lateral, the roof and the windows belong in diligence rather than in a footnote. Tenants are not one group either. Some want the walkable grid and will trade a parking space for it; others want a driveway and a fenced yard. A building that suits one rents poorly to the other, and at this price a single bad vacancy is expensive.
San Rafael needs about two thirds down at the median
The monthly arithmetic is blunt. At 20% down the purchase requires $259,608, the loan is $1,038,433, principal and interest is $6,986, and taxes and insurance add $1,352. That is $8,338 all in against $3,182 of rent, a negative $5,156 every month and a 0.38 ratio. Nothing in that list is unusual for Marin. It is simply what a median house costs to carry at today's rate.
Raising the down payment helps, but slowly. At 35% down the ratio only reaches 0.45. Reaching 0.75 takes 66.9% down, and reaching 1.00 takes 79.0%. Those are not a lender's negotiating position. They are what the arithmetic requires at 7.11%. A buyer with 35% down and a strong income story still fails the ratio, and the program prices that risk or declines it.
The rent side of the correction is worse. At 20% down a San Rafael property would need $6,253 a month to reach 0.75 and $8,338 to reach 1.00. The market rent is $3,182. No renovation doubles a Marin rent, and a plan that assumes it will is not a plan. The gap closes through units, a second lease or a larger down payment, not through a better rent estimate.
The San Rafael structures that close are multi-unit or low-leverage
A duplex to fourplex on a flat street near downtown or the Canal is the most direct answer. Four leases against one loan change the numerator in a way a single house cannot, and the older buildings in those areas trade closer to their income than a hillside house does. The trade is management and condition. Two tenants, two kitchens and two water heaters are more work than one house, and the rent roll has to be legal and documented for the appraiser to use it.
A house with a permitted second unit is the second answer. A legal unit with its own lease adds rent the appraiser can support, and near the median that extra lease is often the difference between a decline and a file that funds. An unpermitted conversion cannot be counted, and it becomes a disclosure problem at resale as well as an underwriting problem now. Pull the permit history before you make an offer, not after the appraisal.
The third answer is a large down payment on purpose. A buyer at 66.9% down is not trying to manufacture a return from leverage. They are holding a long-lived asset with a small loan and a ratio that survives a soft year, and they are accepting that the return comes from the property rather than from the spread. That is a legitimate purchase. It is simply not the same purchase as 20% down.
The fourth is a dated building bought with a bridge, renovated, leased and refinanced into a DSCR loan on the new rent roll. The take-out has to be sized before the bridge closes, against the rent the work will produce. If the stabilized rent still leaves the ratio short, the bridge becomes the exit problem. Underwrite the refinance first and the purchase second, in that order.
San Rafael's real costs sit outside the ratio
HOA dues and vacancy are not in the model denominator. The ratio on this page is rent against principal, interest, taxes and insurance, so an association fee, a month of vacancy, a maintenance budget and a special assessment all sit outside it. On a condo with a meaningful monthly fee, the printed 0.38 is optimistic by a wide margin. Read the association budget and the reserve study before you treat the ratio as an answer.
Insurance is not a formality in Marin. Hillside streets, older wiring and brush exposure narrow the carrier list, and a bound policy can come in well above the allowance the model uses. A website quote is not a policy. Get a binder during diligence and rerun the payment with the premium you were actually offered, then decide whether the file still works.
Property tax reassesses at the sale price under Proposition 13, so the seller's bill describes the seller's basis and not yours. Expect a supplemental assessment in the first year and underwrite the post-sale number from the start. The 1.25% allowance in the model is a convention for comparison, not a prediction of the parcel's bill.
State law caps increases for many covered units at 5% plus the regional CPI change, with a 10% ceiling, and the exemptions depend on the building's age and ownership. If the plan depends on moving a below-market rent to market, confirm the unit's status in writing before you buy it. A rent schedule is a starting document, not proof of what you may collect.

What clears 0.75 in San Rafael
At 7.11%, a median-priced San Rafael rental needs 66.9% down to reach a 0.75 ratio. Keeping 20% down instead, the rent has to be $6,253 a month rather than $3,182.
What clears 1.00 in San Rafael
A full 1.00 ratio takes 79.0% down at the median, or $8,338 a month in rent at 20% down. That is the gap between a San Rafael deal that finances and one that waits.
Model assumptions: 7.11% 30-year fixed, 1.25% of value a year for taxes and insurance, no HOA, no vacancy or maintenance in the ratio. A lender uses the appraiser's market rent and adds any HOA dues, so a real file will move.
Where the San Rafael rental stock actually sits
Citywide medians hide the decision. These are the areas San Rafael investors ask about most, and what to underwrite before you commit to one.
Downtown San Rafael
The county seat's walkable core, with apartments over storefronts, small multifamily buildings and a few newer projects within a short walk of the transit center. Parking is the recurring constraint, and the older buildings carry the maintenance questions. Ask for the roof age, the sewer lateral report and the rent history on every occupied unit before you underwrite a market rent.
Gerstle Park
A grid of older houses and small apartment buildings on small lots, close enough to downtown to walk and quiet enough to keep families. The housing stock rewards a careful renovation, and some lots have room for a second unit if the setbacks and access allow it. Expect long-tenure owners, deferred maintenance and a rent roll that needs verifying unit by unit.
Dominican
A hillside neighborhood of older houses and small apartment buildings above downtown, near the university campus on the north side. The renter pool turns on an academic calendar as much as on commuting, which shows up in lease dates and turnover. Sloped lots, stairs and narrow streets make access and parking part of the underwriting rather than a detail.
Sun Valley
Flat streets west of downtown with ranch houses, duplexes and small apartment courts. Entry prices sit below the hillside neighborhoods, which is exactly what makes the rent-to-price relationship more workable here than in the rest of the city. The stock is older and plain, so a roof, a furnace or a sewer line is a real line item in the first year.
Terra Linda
Mid-century tract houses and small complexes on the north side, with wider streets, real driveways and a suburban feel that holds families for years. Lots are generous enough that a second unit is worth investigating on some parcels. The tenant profile is long-stay, so underwrite fewer turns and a slower rent trajectory than a downtown building.

San Rafael investment property questions
What does a San Rafael rental cost per month at 20% down?
On the median $1,298,041 property, 20% down is $259,608 and the loan is $1,038,433. Principal and interest runs $6,986, taxes and insurance add $1,352, and the all-in payment is $8,338 against $3,182 of rent. That is $5,156 negative every month before vacancy, maintenance or any association dues.
How much down payment does a San Rafael DSCR loan need?
Reaching a 0.75 ratio takes 66.9% down and reaching 1.00 takes 79.0%, at the 7.11% model rate. At 20% down the ratio is 0.38 and at 35% it is 0.45. A cheaper building with more rent per dollar of price needs less. A hillside house at the median needs exactly this.
Can a DSCR loan carry a median San Rafael house?
No. At $3,182 of rent against an $8,338 all-in payment, the ratio is 0.38. A lender looking for 0.75 will decline the file or ask for a down payment near two thirds of the price. The house can still be a reasonable long hold, but it does not qualify on its own rent at ordinary leverage.
What rent does a San Rafael property need to reach 0.75?
At 20% down the property needs $6,253 a month to reach 0.75 and $8,338 to reach 1.00. The median rent is $3,182. No renovation doubles a San Rafael rent, so the gap closes with additional units, a second lease on the lot or a larger down payment rather than with a rent estimate.
Which San Rafael property types actually finance?
Two to four unit buildings on the flat streets near downtown and the Canal, houses with a permitted second unit, and single properties bought with a large down payment. Each of those changes the ratio in a way a median house with one lease does not. A condo with a heavy association fee is usually the hardest file of all.
Does San Rafael have rent control?
Civil Code 1947.12 sets a statewide cap of 5% plus the regional CPI change and never more than 10%, exempting newer construction along with some individually owned houses and condos. Local rules and the unit's rental history decide the rest. Confirm the status in writing before you buy on a planned increase.
Are HOA dues and vacancy part of this model?
No. The DSCR denominator here is principal, interest, taxes and insurance only. HOA dues, vacancy, maintenance and special assessments sit outside it, which makes the printed ratio optimistic for any property that carries them. A lender adds HOA dues to the payment, and the rent it uses is the appraiser's market rent rather than your lease.
What does a 2.94% gross yield mean in San Rafael?
It means a year of rent covers under three percent of the purchase price before any expense at all. The median rent is $3,182 against a median value of $1,298,041. Once taxes, insurance and debt service are paid, the property depends on the buyer rather than on the rent. That is what a yield this low describes.
Will a second unit count toward San Rafael DSCR income?
A permitted unit with its own lease can be included in the market rent the appraiser supports, and it is often what makes a San Rafael house work. An unpermitted conversion cannot be counted, and it can complicate the appraisal and a future sale. Pull the permit history for the property before you make an offer.
Why is the San Rafael ratio worse than the rent suggests?
Because $3,182 is a high rent in absolute terms and a low rent against a $1,298,041 asset. The payment on the loan at 20% down is $6,986 before taxes and insurance. San Rafael is priced for buyers who want the county seat, and the tenant paying for the address is not paying enough to service the debt on it.
Ready to put a San Rafael deal in front of a lender?
San Rafael does not finance itself at the median, and a page that says otherwise is selling something. It does finance a fourplex on a flat street, a house with a permitted second unit, or a low-leverage purchase made on purpose. Send the address, the leases and the down payment, and the arithmetic will show which of those you have.
