So as a pure investment, the facts that Costa Rica is a beautiful country and a popular tourist destination shouldn't matter if they don't make you any money.2.

I have started managing my grandparents rental properties, and they have never preformed background checks or any pre-screening for tenants.

Once you are in southwest NC / southeast TN you are within a couple hours of the 3 states and the whole area is beautiful.

I just need to listen to the spreadsheets and not the beautiful stonework of the more expensive parts of town

My background in technology (ssserv.com) provides marketing and branding experience for lead generation. 

The differences are: 1) "my" house has the additional 15 acres. 2) "my" house has 2 bathrooms~neighbor's house has one. 3) "my" house has a beautiful view of the valley.Erie PA has a slowly declining population.

We can only charge $20 for a back ground check.

Is there a standard application I can use for this new tenant to fill out available, and any recommendation of site to use for background/credit check?

Heavy construction background and willing to do 100% of rehab labor myself.

It sounds like you have plenty of background experience in RE.
