I've worked with several local builders on behalf of buyer/clients.  

Hey Everyone,Thank you for the support.

Everyone here has been really supportive and I've been finding a ton of value so far

That will affect the value of your lease as well.Typically best to worst as example backing the lease:Taco Bell:Yum brands corporate guarantee (10,000 plus stores)Subsidiary of YUM brands corporate ( example 10 states and 600 stores)Large franchisee ( long time operator with say 100 plus units and decades as an operator)Small Franchisee ( a couple to maybe 5 units etc.)Non- brand tenant (Joe's Taco's) that has no franchisor or support system.   

Its been difficult meeting broker and clients who are interested in it.

If you can support this the hassles should be less than lower class areas and the returns in a few years down the road could be great. 

and how does your company sustain overtime with these "lifetime" warranty as if the customer experience any problems with foundation, you will be called and you will have to provide the support. 

I have a goal of 10k mailing a month once I get my business that was once on life support back on the road to recovery.  

I have also handled landlord/tenant issues and contract drafting for my clients.

What I wrote above does not create an attorney/client relationship between us.
