What is the 2026 conforming loan limit in Cook County, IL?

$806,500 for a one-unit property. Loan amounts above that move to jumbo or portfolio investor pricing. On a DSCR purchase at the county average basis of $350,800, an 80% LTV loan is roughly $280,640, so most files here stay inside the limit.

Which Cook County market has the best rental cash flow?

On current modeling, Harvey shows the strongest coverage in the county at about 1.06x, with an estimated $900/month lease against a $110,000 basis. Harvey offers the lowest entry price at $110,000. Both are worth modeling on a specific address before you choose a submarket.

Can I use one DSCR lender across multiple Cook County properties?

Yes, and it is usually the faster path. DSCR loans have no cap on financed properties, so once a lender has your entity documents, guaranty and reserve verification on file, subsequent acquisitions in Cook County close on the same underwriting profile — typically 21–30 days per file, with the appraisal on the critical path.

Do property taxes in Cook County affect my DSCR ratio?

Directly. County-assessed taxes sit inside PITIA, which is the denominator of the ratio. At the $350,800 county average, taxes and insurance are already built into the $2,711 monthly PITIA figure above. A reassessment after purchase can move a 1.05x file below 1.0, which is why we underwrite to the reassessed value rather than the seller's current tax bill.

Investing in Cook County

Cook County covers 25 rental markets we actively finance in Illinois — Arlington Heights, Berwyn, Blue Island, Calumet City, Chicago, Chicago Heights and 19 more. Across those markets the median investment basis averages $350,800, a long-term lease averages $1,964/month, and the average all-in PITIA on a DSCR loan at the minimum down payment is $2,711. That produces a county-wide average DSCR ratio near 0.76x.

Basis varies more inside Cook County than the average suggests. Harvey is the lowest entry point at roughly $110,000, while Harvey currently models the strongest coverage ratio in the county at 1.06x. When two towns in the same county ratio differently, it is almost always the rent-to-price relationship rather than the rate — the same loan pricing applies county-wide, so the deal is won on which submarket you buy in.

County-level inputs that move your ratio

Everything in Cook County shares one set of county-level inputs, and they matter to your ratio: the 2026 conforming loan limit here is $806,500, county property tax is assessed and collected at the county level, and recording and transfer charges at closing are set by the county clerk. Those three items are the reason a DSCR file that pencils in one county can fail two counties over at an identical price and rent.

3 of the 25 markets here support meaningful short-term rental revenue, so an STR-qualified DSCR file is a live option in Cook County — expect 25% down, six months of reserves, and address-level permit verification before you go hard. Average estimated cap rate across the county is 4.38%.
