Need help Assessing a deal

[Jose Rodriguez]

I have a 1,135 sq ft single family home I’m looking at in Pennsylvania. 2 bed(potential 3 if we fix up the attic a bit) 1 bath small backyard and the property seems to be in mint condition. The current tenant maintains the property and pays 650$ a month plus utilities. Taxes are 900$ a year and garbage and recycling which I believe is tied up into the 900$ annual tax. It’s listed at 42,900. Zillow estimates the property at 40k. I’m am able to buy cash no loan, what should I be looking for? Is this a good deal anyone
