Those with real subject matter expertise get the year 1 return that no longer exists in more mature national park markets. 

If so, make sure agreement is in writing, signed by both parties, specifies new end date and ensures any existing security deposit will still be dealt with properly per landlord/tenant laws, and I'd also ask for a partial payment to be issued at signing to make obtaining his new place easier.  

@Kerlous Tadres - just as an FYI, duplexes basically don't exist in Huntsville relative to the number you may see in your home city.  

Not a ton, but they exist.

Just prior to close build a new listing and block existing booking dates. 

What options exist when they don't want to tell you their names?

If it protects building by not shifting ground I will replace with concrete one.How to find how much life is left with existing retention wall?

The problem has existed for decades but with population growth, it has gradually gotten worse.  

If I buy a small business that includes real estate, it is possible to assume the existing loan (at a lower rate), and finance the additional amount up to asking on a second position mortgage?

I wish that existed when I went to UF!
