i don't wan to make it complicated for the tenant or me. 

This site is an invaluable source of information.

Does the owner live on-site?

@Joe VilleneuveOffering rent credits is really great to sell properties fast but I have also heard there are legal complications related to that.One thing that i can think of is giving Seller concession instead of rent credit. 

Once I have that information, I usually will go over to the property appraisers site to get the owners information and then ride by the property to see if it is vacant. 

I feel as if I'm over complicating things, but being my first purchase i'm trying to account for my inevitable mistakes. i would rather have cashflow over anything.  

It is more complicated than that, but you get the idea. 

If they start demo,and then never get back to that site, you're in a bad position as you've put in 100% and now have to put in 100% of the rehab as well when you take it back.  

whatever you stance on that, it has created a situation where we (americans) look down on factory built homes.Without the artificial input I believe we would have giant , efficient, factories in every city pumping out modular homes, that are green, affordable and accepted as "normal" and probably cost as much as a nice new truck.If you have ever built a new home, the insanity of "site built" becomes apparent as the waste of materials and man hours can be staggering.

Search the owner name, work backwards thru property appraiser/clerk if court site.
