This study quantifies how Nigeria’s mortgage institutions relate to real-estate industry performance using a compact log– log OLS model on annual data (1995–2023; n = 29). Sector performance is measured as real value added at basic prices, with institutional channels captured by Federal Mortgage Bank of Nigeria disbursements (ln[FMBN]), Nigeria Mortgage Refinance Company refinancing/bonds (ln[NMRC]), and Family Homes Funds programme finance/units (ln[FHFL]). Diagnostics indicate good model behaviour (no problematic collinearity; variance inflation factors < 5). Overall fit is strong, and the omnibus regression is significant. Coefficients are interpretable as elasticities: NMRC shows the largest and most precise association with sector performance, FHFL is positive and statistically significant, and FMBN is positive but imprecise at the 5% level. These results rank practical levers for policy and management: anchor secondarymarket liquidity through NMRC to stabilise funding costs and tenors; convert FHFL flows into verified delivery through milestone-linked governance; and strengthen FMBN eligibility, cadence, and transparency so concessional finance becomes a consistent sector-level driver. The study recommends prioritising scaling and regularising NMRC to anchor liquidity and pass refinancing gains into longer tenors and lower primary-market rates; hard-wire FHFL funding to milestone-verified delivery with standardised developer selection, offtake agreements, and independent monitoring; and strengthen FMBN governance and cadence, including progress-linked tranches and routine public microdata, to convert concessional flows into consistent, measurable sector gains.
