An outstanding claim that amounts only to a cloud on title is a continuing cause of action and is not barred by lapse of time until the hostile claim is asserted in some manner so as to jeopardize the superior title.

Putting a lease on the property clouds title as a leasehold interest and any bonafide leasehold interest must be upheld after foreclosure for up to 6 months under recent federal law.

you have to answer these questions, and be solid with these numbers.that's where your realtor can help - and like chaser said - get a good competent realtor.

A rider is placed on signage as well on the property, notice that it's under contract which clouds your offering it for sale.As a FSBO, you can use a sign rider or pull the sign.

That remains a cloud on the title but it is easy for the owner or the city to get a judgment dismissed in that situation. 

Plus you can take pictures of your receipts and they store them on the cloud.

Wanted to post this article that does a good comparison between Avail and Tenant Cloud (and Cozy) mentioned here.

Once a property is under contract and then falls out, it leaves a little black cloud over it for the next buyer.

The company was using tenant cloud and later switched to a different rent manager program.  

That's pretty impressive to give up the full time gig to chase RE.
