Student housing near major universities generates consistent rental demand, but the right financing structure depends heavily on your income profile, portfolio size, and how the property is leased. DSCR loans and conventional mortgages serve different borrower profiles, and choosing the wrong one can cost you the deal or erode long-term returns.
How DSCR Loans Work
Debt Service Coverage Ratio (DSCR) loans are a category of non-QM (non-qualified mortgage) financing. Instead of underwriting based on the borrower's personal income, lenders evaluate whether the property's rental income covers its debt obligations.
The DSCR formula is straightforward:
DSCR = Gross Rental Income / Total Debt Service
Most lenders require a minimum DSCR of 1.20, meaning the property generates $1.20 in rental income for every $1.00 of mortgage payment (principal, interest, taxes, and insurance). Some lenders approve loans at 1.0x or even below 1.0x (called a "no-ratio" DSCR loan) at higher rates and stricter LTV limits.
DSCR Loan Qualifying Criteria
- Minimum credit score: typically 620 to 680, depending on the lender
- Down payment: 20% to 30% for most loan programs
- No personal income documentation (no W-2s, tax returns, or pay stubs)
- Property must be non-owner-occupied investment property
- Eligible property types include single-family, 2-4 unit, and many lenders accept 5+ unit properties under portfolio DSCR programs
Rates on DSCR loans generally run 0.5% to 1.5% higher than comparable conventional investment property loans, reflecting the reduced income documentation and non-QM structure.
How Conventional Loans Work for Investment Property
Conventional investment property loans conform to Fannie Mae and Freddie Mac guidelines. Underwriting centers on the borrower's financial profile: credit score, debt-to-income (DTI) ratio, verified income, and assets.
Conventional Loan Qualifying Criteria
- Minimum credit score: 620 for investment property; 740+ for the best rates
- DTI ratio: typically capped at 43% to 45%
- Documentation: two years of tax returns, W-2s or 1099s, two months of bank statements, and asset verification
