INVESTMENT ANALYSIS
Investment Verdict
Appreciation PlayYield and appreciation often trade off, and at 10 Summer St #1, Boston, MA, 02129 in Boston the bet is firmly on appreciation. Rental yield 3.58%. The 3.58% gross yield on a $1,699,000 price is below income-first thresholds, but 5%/yr value growth projects $469,402 in equity by year five. Ziffy Mortgage's non-U.S. DSCR mortgage (0.66) 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: $282,171.
