Loan pathways
Explore by Topic
Every deal takes different debt. Start from the strategy — buy-and-hold rental, flip, bridge-to-stabilize, ground-up build — and compare structures grounded in published lender terms, not marketing copy.
DSCR Loans
Debt-service-coverage-ratio loans that qualify on property cash flow instead of personal income — the workhorse of rental-property financing.
ExploreFix & Flip Loans
Short-term rehab financing for purchase plus renovation, sized on after-repair value and paid off at sale or refinance.
ExploreBridge Loans
Interim financing that closes fast and buys time — between acquisition and stabilization, or between one exit and the next.
ExploreHard Money Loans
Asset-based private lending priced on the deal, not the borrower — faster and more flexible than banks, at a higher cost of capital.
ExploreRental Portfolio Loans
Blanket and portfolio facilities that finance multiple rental properties under one loan, one payment, and one set of covenants.
ExploreCommercial Mortgages
Permanent debt for income-producing commercial real estate — office, retail, industrial, mixed-use — from banks, agencies, and debt funds.
ExploreConstruction Loans
Ground-up and heavy-rehab construction financing: draw schedules, interest reserves, and completion guarantees explained.
ExploreLand Loans
Financing for entitled and unentitled land — the hardest asset class to leverage, and the one with the widest lender-to-lender terms.
ExploreMultifamily Financing
Debt for 5+ unit residential assets, from agency (Fannie/Freddie) small-balance programs to bank and bridge executions.
ExploreShort-Term Rental Loans
Financing underwritten on STR revenue (Airbnb/Vrbo) — which lenders count projected nightly income, and on what haircut.
ExploreInvestor HELOCs & 2nds
Second-lien and line-of-credit options against investment property equity — business-purpose only, distinct from consumer home equity.
ExploreLender Reviews
Research-based reviews of investor-focused lenders: published terms, state coverage, documented processes, and the fine print.

The foundation
Build your decision on solid ground
Model the debt service, check the coverage ratio, and read the lender’s actual terms before you sign — a mispriced loan quietly eats the whole spread on a deal.
Affiliate disclosure & editorial stance
Keystone Rate is an independent research publisher — not a lender, broker, or financial advisor. We may earn a referral commission when readers connect with partner lenders or marketplaces through our links, at no extra cost to you and with no effect on how listings are ordered (we sort by published terms, lowest advertised rate first). Our research covers business-purpose, investment-property financing only — we do not cover or advise on owner-occupied consumer mortgages. Everything here is based on published rate sheets, lender disclosures, and program guidelines, not on personally applying for these loans. Every figure is an illustrative estimate, not a quote or commitment to lend; terms change constantly. This is general information, not financial, legal, or tax advice — confirm current terms with the lender before you decide.
