@Riley Yourdon make sure you put in your purchase contract that you will get the leases and rent ledgers BEFORE closing so you can review them.At closing you'll want to require that you get the tenant names, phone & email.There is this thing called fraud when it comes to leases & ledgers, so discuss reps & warranties with your agent.

@Paco Rabi,It's definitely nice to have existing tenants in place because they will be paying rent as soon as you close!

@Guertone Sutton, how far along is your team assembled (agent, wholesaler, contractor, lender, closing attorney)?

How close is the town to a city?

There is always rental demand, and being close to Philly is solid.

For a good duplex in Tosa or West Allis that is 15-20k including closing cost. 

I have made several great connections on BP from contractors to many millions in closed deals from house hacker clients.

Allentown is a great city, lots of jobs, great infrastructure, Close to many attractions, but its gotten too expensive.

After doing some internet research this is pretty close to what I have discovered. 

I made an offer within a few days of it coming back online and closed 4/21/2017 at $44,000 below the original listing price in less than 30 days.
