INVESTMENT ANALYSIS
Investment Verdict
Appreciation PlayYield and appreciation often trade off, and at 819 S Humboldt St, San Mateo, CA, 94402 in San Mateo the bet is firmly on appreciation. Rental yield 4.06%. The 4.06% gross yield on a $1,398,000 price is below income-first thresholds, but 5%/yr value growth projects $386,242 in equity by year five. Ziffy Mortgage's non-U.S. DSCR mortgage (0.75) finances the acquisition on rental income alone. A larger down payment (30–35%) reduces monthly debt service and tightens the spread. Total projected cumulative return: $277,927.
