Don't forget the wild card of President Trump closing the southern border some other nutty trade policy.

I bought a 4000sq ft Duplex (4 bdrm, 2 bth  x 2), 8 minutes from Greektown and 10 min from the border.

Not when you live 10 mi south of the WI border :-) and not when you get $3300 in rents on a fourplex under $200k.

Capital has no borders.

We always check the county recorder for the deed/title of the property the tenant is leaving to cross check the owner against the name supplied by the prospective tenant. 

Just be sure to dot the "i's" and cross the "t's".

Apparently she was told that she didn’t have to pay the pet fee by her previous landlord and that it was crossed out in the lease agreement.

I think you can still get good deals in surrounding areas, as Heather mentioned, and I am partial to areas just over the Rhode Island border where the courts seem to be more landlord friendly anyway.   

These are similar to the issues Canadians face when purchasing real estate in the U.S.A.I would advise you consult an attorney and accountant with cross-boarder expertise before you invest as they will help you choose an ownership structure which best meets your needs.

Many of those Avon school ones on the border do have Indy addresses so it might have some stigma for buyers because the address is not Avon/Plainfield.
