@Marc Shin We're funding cash out refis for a lot of our most experience BRRRR clients right around day 91 (to pass 90 days of title seasoning) where we get the process started (appraisal, title, application, etc) around day 60  (plus or minus) when they have the place fully renovated and at least listed for rent (we'll use appraisers opinion of market rent to calculate DSCR). 

You calculated 8 turns a month?

Just enter the address of whatever property you're looking at and the site calculates the market rents 

I use words calculatedly for a living. 

I do some pretty crazy things (by other's opinions), all carefully calculated risks by the way, but I can't imagine what you've been through.

Quote from @Sean O'Keefe:In your article you said, We had a recent court case which said in black and white: you cannot calculate an average if you do not have at least two numbers to average.Can you provide the court case reference? 

Learn from this experience & do some simple calculations to find a good rental rate. $1200 at 1.5 months vacant will yield a greater annual EGI ($12,600) than $1350 with 3 months vacant ($12,150).

Since you plan to keep it the ARV doesn't matter in this calculation.

Make sure to also include in your calculation all the associated costs of those homes (maintenance, cap-x, management, vacancy, etc) then include the selling cost of the home since the appreciation isn't unlocked until you sell the home.

In my experience, most of the online calculators are just taking an educated guess for you.
