Brrr in Philadelphia

[Maxim K.]

Hello there , I'm new Real estate investor and only have 3 doors so far. I'm looking to expand my portfolio and want to try BRRRR in Philadelphia area. I see a few properties that make sense to get and spend little in renovations . my questions are:

1. how do I know I would be able to get a rent I’m looking for ? And how long will it take to find a tenant ? ( so far using comps listed on Zillow rentals )

2. How do I know I would be able to get appraisal value I’m aiming for ? Zillow recently sold ?
