I'm Martin Maxwell, and this is part two of our language series. Last episode we covered the five terms every investor must know. Today we're mapping 10 terms to the five PRIME phases — Prepare, Research, Invest, Manage, Expand. Master these and you can read any deal, any market, any offer.
Prepare Phase: Credit Score and DTI
Before you look at a single property, lenders look at you. Credit score — 620 is the floor for most investment loans, 740+ gets you the best rates. DTI (debt-to-income) — your monthly debt payments divided by your gross income. Lenders typically want 43% or below. A $6,000 monthly income with $2,200 in debt payments? That's a 36.7% DTI. You're in the green.
These numbers determine what you can borrow. Fix your credit, pay down debt, or increase income before you fall in love with a listing. A 720 credit score with a 38% DTI opens doors. A 650 with 45% DTI closes them.
Research Phase: Cap Rate and Cash-on-Cash Return
You've got 100 listings. How do you filter? Cap rate and cash-on-cash return. Cap rate tells you what the property earns relative to its price. Cash-on-cash tells you what you earn on the money you put in. A 6% cap in a 5% cap market might mean value-add. A 4% cap in an 8% cap market might mean overpaying. Know your market's range.
The investors who move fastest filter by these two metrics first. Cap rate weeds out overpriced listings. Cash-on-cash weeds out deals that don't cash flow for you.
Invest Phase: LTV, DSCR, ARV
You've found a deal. Now the financing. LTV — loan-to-value. 75% LTV on a $150,000 purchase means $112,500 from the bank, $37,500 from you. DSCR — debt service coverage. Lenders want 1.25 — your NOI has to cover the mortgage by 25%. ARV — after-repair value. For BRRRR and flips, this number makes or breaks the refi.
One mistake I see: investors assume ARV based on Zillow or a guess. Get a real appraisal or a broker price opinion from someone who knows the comps. A $20,000 ARV miss on a BRRRR can kill your entire refi plan.
Manage Phase: NOI and Vacancy Rate
You own it. Now you run it. NOI — net operating income. The property's earnings before debt. Track it monthly. If it drops, you've got a problem. Vacancy rate — the percentage of time units sit empty. 5% is healthy. 15% means you're bleeding. A $1,200 rent with 10% vacancy costs you $1,440 a year. That compounds: high vacancy often means longer turnover, more turnover costs, and a hit to your NOI that lenders notice when you try to refi or sell.
Expand Phase: Equity and 1031 Exchange
You've built wealth. Now you scale. Equity — the difference between what you owe and what the property's worth. $200,000 value, $120,000 loan? You've got $80,000 in equity. That's down payment money for the next deal. 1031 exchange — sell one property, buy another, defer the capital gains. The IRS gives you 45 days to identify a replacement and 180 days to close.

NOI (net operating income) is what a property earns from operations each year. Rental revenue minus vacancy loss and operating expenses. Before you subtract the mortgage, CapEx, or taxes.
Read definition →Cap rate measures a property's annual net operating income as a percentage of its purchase price or current market value, assuming an all-cash purchase.
Read definition →Cash-on-cash return measures your annual pre-tax cash flow as a percentage of the total cash you actually invested in a property.
Read definition →The ratio of a loan amount to a property's appraised value, expressed as a percentage — a 75% LTV on a $200,000 property means a $150,000 loan and $50,000 in equity.
Read definition →A ratio that measures whether a rental property's income covers its debt payments — calculated by dividing rental income by total debt service (PITIA), where 1.0 means breakeven and 1.25+ means strong cash flow.
