I've been wondering the same thing actually.

I was wondering what is the best way to screen future tenants if I don't want to pay for a monthly subscription like tenant cloud or rentredi? 

Something that cuts through the noise and provides me with the essential metrics necessary to assess the quality of a potential investment quickly and efficiently.I'm open to suggestions and advice from those who have navigated similar paths.

It's wonderful and exciting but scary too. 

This could indicate a premium market with potentially higher profit margins on flips.Housing Structures: Zip code 13224 shows a high number of multi-family structures, particularly those with more than 50 units, suggesting a potentially saturated rental market or a demand for apartment living.Market Outlook Combined with Google Search Data:13224: Witnessing a notable 53.7% surge in median sale prices for 4-bedroom homes and a 19.7% uptick for 5+ bedrooms reflects a buoyant market for larger residences.

"Home" suggests it will be for personal use.

Can anyone suggest a market where one-bedroom STR's that are nicely designed do well?

Would you suggest hiring a company like Healthtrust to do the feasibility research for us or is there a less expensive option?

I'd suggest not noting things like "stabbed coach with a knife" and instead "7" long cut in left cushion of couch" and "4 sq ft area of carpet under den window coated in an unknown substance that stained the carpet". 

I suggest you take a few trips out to Philly and explore the different neighborhoods to determine where in Philly you want to invest and what areas you want to avoid.
