Find Brandon's videos on YouTube for the "four square" method of analyzing homes and practice.

That creates a compelling opportunity for investors willing to get in ahead of the curve.I’ve been investing there since 2019 and have built a 12-door portfolio primarily using the BRRRR method.

Best practice is to keep one or two payments in reserve from the buyers down payment for such instances.

I know in residential lending you can get a HELOC to borrow a down payment to buy another property.

Hi Pixel, Check out this article about how DSCR loans play into the refinance part of the BRRRR method.

On the lease, he'll pay me $100/m over my HELOC payment and all other expenses, including the refi cost, inspections, title work, etc... 

Direct communication with the builder has been the most effective method in my experience.

Or a seller finance calculator showing the monthly payment based on negotiated price, interest rate, down payment, etc.

Quote from @Jaycee Greene: Assuming you pay asking price, I'd estimate the down payment for something like that using a hard money loan (HML) would be around 40% of the purchase price and your monthly payment would be $2,600 with an interest rate in the low 7% range (probably need a 700+ credit score to get that).

Consider tenant stability, including consistent payments and maintenance of the TOH.
