I just couldn't believe it and decided to do some investigating.

Hello Mohammad,Tax Sale investing can be rewarding but you are right to want to investigate the potential pitfalls first.

if the city or county has it on a demo list and records it against the property it will come up on a preliminary title search. other wise just go to city and county and ask for their demo list.

I'm still early in my own preliminary research, so I'd love to hear some first-hand landlord experiences of collecting pass-due rent, removing tenants from the property, evictions, and overall impressions of the landlord-tenant environment. 

Any recommended due diligence beforehand (preliminary title report, walk the exterior, analyzes the Neighboor and comps, etc)?

The reality is, nobody investigates the podcast guests to see if their claims are true.

The high-crime cities I’ve investigated have declining populations.

I don't know anything about taxes but would definitely want to investigate it.If I buy a property in Italy and use it as a personal vacation home and a rental, it seems I could keep all the money in Italy and it wouldn't be subject to American taxation.

Ill add a lot more to it but it tends to be deal to deal based information I gather from the other side and investigating the property itself. 

What is on the preliminary title report?
