Setting rent — the comps and the math that actually matter.

Rent is the only number on your investment that you set. Get it right and every downstream metric — cash flow, return on equity, time to next refi — works. Get it wrong by 5% in either direction and you've either priced the unit into a long vacancy or locked yourself under market for a year. The process for landing on the right number isn't mystical; it just requires pulling real comps and running the vacancy-adjusted math once.

Section onePulling real comps

Zillow Rent Estimate is a starting point, not a number. Pull the last 30 days of leased comps — same bedroom count, same approximate square footage, same school district, same walkability — from Zillow, Apartments.com, and the local MLS rental feed. Five comps is the minimum; ten is better. Look at what rented, not what's still listed, because what's still listed is often overpriced. The median of your leased comps is the honest market rate.

Section twoSeasonality is real

Rental demand in most U.S. markets peaks June through August and bottoms December through February. A unit listed in January rents for less, and slower, than the same unit in June. If your lease end-date is falling in winter, consider a 14- or 16-month lease on the next turn to shift the renewal into peak season. That one decision, compounded over five years, can add months of avoided vacancy.

Pricing above market is a bet against math. The bet usually loses.

Section threeVacancy math that kills the top-of-market strategy

Suppose market rate is $2,000. You list at $2,100 hoping for a premium tenant. The unit sits an extra month, then rents at $2,050. You made $50 more per month but lost $2,050 in vacancy — a net loss of about $1,450 over the year. The math almost always favors pricing at market and renting fast. Pricing above market only works when demand clearly exceeds supply and when the top tier of tenants is actively shopping; most markets most of the time don't clear that bar.

Section fourWhen to raise rent, and by how much

A good tenant who stays is worth roughly one month of avoided vacancy plus the turnover costs — call it $2,500 to $4,000 in most markets. Don't chase the last 3% at renewal and lose them; the math rarely justifies it. Raise 3–5% most years to stay roughly at market, and only push 8%+ if the unit has fallen meaningfully below market. Give 60 days' notice even where state law only requires 30.

Section fiveWhen to cut your price

If the unit has been on-market for two weeks with fewer than three serious showings, the price is wrong. A small cut — 2% to 3% — resets the algorithmic listings and brings in fresh traffic. A big cut looks desperate and often attracts worse applicants. Cut once, cut decisively, and stop; multiple small cuts stretch vacancy and signal weakness.
