In a situation where you were doing an arbitrage (renting it from the owner, then yourself re-renting it to someone else) your costs to renovate/fix it up while you're using it would be able to be capitalized and depreciated by you once your rental was in service (available for rent to others).

EDUCATE YOURSELF - yes, it will take time, but will lead to a selection that better meets your expectations & avoids potentially costly surprises!

Start by leveraging your skills to identify undervalued properties, perform cost-efficient renovations, and build sweat equity.

You do that then you could have a lot of cash available to finance your next purchase and perhaps renovation costs as well.
