The spec-versus-resale label barely changes the analysis. What matters is cash-on-cash return: how much money you put in, and what that capital actually earns each year. Michael Zuber's book One Rental at a Time has a useful rule: don't buy alligators, meaning properties you have to feed money into every month. If a spec home only pencils with the builder's buydown and bleeds cash without it, that's an alligator wearing an incentive. A few grounded points: - Builders generally aren't slashing prices. They control supply to protect pricing and compete on rate buydowns and finish upgrades instead, so don't assume a big discount is coming. - We lean against letting a buydown drive the decision. It's a sweetener on a deal that already works, never the thing that turns a bad rental into a good one. If you want to see the buydown math anyway, we'll run that comparison for you. - When a property won't pencil as a long-term rental, which is common in high-cost markets, it can still work as a flip: buy, add value, sell to an end user, and potentially roll the proceeds from several flips through a 1031 exchange into a larger down payment on a rental that does cash flow. That's a strategy we actively use. Nobody can promise appreciation, so underwrite the deal on the return you can see today.
