The American Para-Legal Association covers these matters, also called a straw-man transaction. 

Just because they are giving you 30 days notice does not release them from liability under a TAR leaseWhat penalty is listed under Para 28 B 4 for you having to secure a replacement tenant ?

The first paragraph doesn't mention any problems, the second para starts out sounding like someone (buyer) had asked for something from you!

-bem-

Anyway, to your 2nd to last para, yes you can do it. 

Hi Para, I would say run it through the rental property calculator under "Tools" (and you will see a few more categories to think about, like capital expenses), but right off the top of my head look at these numbers (as the calculator is only as good as the input)...

@Nathan BrooksI have 2 paragraphs in my P&S agreement under "Purchase Price"(this is not the complete verbiage, just a summary of what is in my agreement) Para 1: sum to be paid at closing: $xxxx, classified as back payments/legal fees..etc or "balance due at closing $xxx (excluding seller closing costs, prorations..etc). 

Sometimes a para legal will assist as boots on the ground cheaper than a lawyer.
