The potential damage will eat up your profit compared to a standard rental unit.  

Replacing the floors will definitely eat into my ROI now.

However, when my buyers use hard money, it frees up capital so that they can get multiple projects going at once.When it comes to hard money, you eat away at your profit margin with interest, inspection fees, and origination fees.

And it would be illegal for me to pass that fee on to the renters, meaning I would have to eat a fee for every payment.
