Renovations, need help with appraisal percentages
I bought my first income property. Using the BRRRR method. Now I'm going through the rehab costs and the numbers are fair (learning curve forsure) I was wondering if there was any way or means to find out how much percentage of return based on rehabbing certain things such as (paint, flooring, bathroom etc.)
Ex.
Fresh paint, repaint baseboards would have an average return of %% after refinancing.
I just wanna know if there is any general rule of thumb. Thanks a lot!
