Hello Moe, there are some places in the US that are called non-disclosure states.

Full Disclosure: I don't get paid to promote Martel Turnkey.

Some of which is the required disclosure for lead-based paint.

If the property was built before 1978, you should also make sure you have copies of the lead disclosure forms signed by the landlord and tenants.  

Check with utility comps before doing anything of course.I've never gone after a prior seller for non-disclosure, but I'd wager many investors here at BP has.

Alternatives for keeping costs low if you must have passive investors in small deals are: Make sure all are accredited so that you aren't required to have a disclosure document (e.g., a Private Placement Memorandum); or Keep everything (investors, you, and the property) all in one state as you may be able to follow an "intrastate" securities exemption, whose rules may be less onerous than the federal exemption requirements under Regulation D, Rule 506; and Don't even think about advertising - only make offers to people with whom you have established substantive, pre-existing relationships. 

We are a non-disclosure state.  

Awning is a great, free tool for pulling comps (disclosure - I used to work there).
