I was speaking with a realtor here in San Antonio.

I went there yesterday to see if I could speak with the homeowner and pay the taxes and give him a fee on top of it in exchange for the property but he is kind of out of his mind.

Generally speaking though, most states require a person doing business to either; open a new business or register their own business, unless they are operating under certain types of organizational structures.

Practically speaking, you should at least call the various government offices that may have information about liens.

I think for protection purposes you should speak to either a RE Lawyer or a wealth conservation specialist. 

These are good for pretty quick analysis like you speak of.Otherwise use the rental calculators on BP to go more in depth.Good luck!

Whether you live in NJ or outside of the state, I'm interested in speaking.

Leave your credit card at home if a guru is speaking. 

You'd evaluate comps, speak with realtors, and document your findings.

Would love to speak with any realtors/wholesalers/property mgmt companies that are knowledgable about these rental markets.Thanks
