Rehab Costs / Business exprense?

Hi BPers!!

I've recently been on the Forums asking about using the BRRRR Strategy, and have had some great insightful discussions.

My next question is Rehab costs and business expense.

If I use the BRRRR way, and I use my money for the Rehab costs, then is that cost considered a business expense, and would I recoup a percentage of that cost in the coming tax season?

Is that how it works?
