INVESTMENT ANALYSIS
Investment Verdict
Appreciation PlayYield and appreciation often trade off, and at 403 W 1st St UNIT 203, South Boston, MA, 02127 in South Boston the bet is firmly on appreciation. Rental yield 5.09%. The 5.09% gross yield on a $1,450,000 price is below income-first thresholds, but 5%/yr value growth projects $400,608 in equity by year five. Ziffy Mortgage's non-U.S. DSCR mortgage (0.94) 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: $326,022.
