If the property is homestead, by statutes  only liens over $250 can be sold, liens under $250 will automatically be held by the county.Most of the liens held by the county that are not homestead are useless piece of land.If you don't believe that the liens will be redeemed, you will have to request a tax deed sale before the 7 years deadline.

Act and the statutes have been modified by case law.I made a **lot** of money doing pre-foreclosure fix & flips in Washington, and was trucking along quite nicely, then this law (below) came into effect.

Ok, I'll start out by saying my answer is based on the statutes in Alaska, so they may not apply to you... and it's been a while since I've read them, so I may not get things quite right.1st... if you sign a lease based on a 30 day billing cycle, and they pay multiple months up front, the 2nd and 3rd months rent would be considered 'prepaid rent', which you might be supposed to give back to them if things break down.  

Specific laws, in fact, have been passed to make sure that buyers are informed of especially important information, including things like property taxes – See Florida Statute 689.261.Other issues, however, are not specifically required to be disclosed to the buyer under Florida law – for example Florida Statute 689.25 regarding disclosure of any homicide, suicide, deaths, or diagnosis of HIV or AIDS infection in an occupant of real property.

TomYou can (and should) read FL Statute Chapter 83 (Landlord-Tenant Act) for everything you need to know regarding landlord rights and responsiblitied (as well as tenant rights and responsibilities), however, her is a "clip" from that statute stating what landlords "must" provide. 

I'd make sure you know how the statutes read before pursuing anything.

@Vernon Gray here is a copy of the ohio statutes.

confirmed, California is mandated by statute, 50/50 split of community property.

Wholesaling without a real estate license in Wisconsin is illegal, you are required to have a license by the state statute definition of brokering. page 1 of the link has the definition of "Broker" and these activities require a license, However if you take ownership thats a different story, then you are limited to the number you can sell without a license.
