$4000/m on $0 what is my ROI?

[Vadim Babets]

I'm NOT bragging #Celebrating, 

I just finished building new construction house from ground up.

House with ADU, I did BRRR. Build, Rent, Refinance, Repeat

I spend approx. 500k building the house, refinanced with 500k conventional loan @ 3.36%,

monthly rent 7,050 for both units, -2,800 mortgage, insurance, & tax. -250 maintenance =$4,000

I did a lot of work myself and I'am a general contractor so I saved about 150K Building this house but still even at 650k its pretty insane ROI
