I have talked to a lot of different ones and have found one that I really like because they have been doing it for twenty years and have vertically integrated property management and construction and a construction warehouse for fixes and everyone is on-staff.

just don't do a lease. as others have mentioned, this forces the buyer of the property to take over the lease (if its even allowed/ they qualify) and it certainly does make the property a little tougher to sell. i'm also doing a house hack, and here in CA, its made a world of difference for me. the bulk of our energy usage is in the summer when we want to run the a/c. my bill stays a constant $228/mo (i pocketed the tax credit and simply financed the panels after that grace period). instead of getting an $800 bill in the summer months, we run the a/c at a constant temperature 24/7 on auto, stay comfortable, and i typically get a little bit coming back at the end of the year. don't expect to pocket this "little bit back" by being conservative with your useage, it sort of is a use-it-or-lose-it situation... i think i got $54 back this year.

San Diego official temperature seldom is above 90 degrees.  

Wood has an ignition temperature of about 700F.

What I really want to do is add 15k sf to the existing warehouse.

I appreciate the info; this is helpful on getting a temperature on what would be realistic. 

Amazon is currently building a gigantic distribution center/warehouse here that should be completed in a few months.

The notes are all on commercial properties (office, warehouse, shopping center, mixed use or sometimes multifamily)The properties are either vacant or occupied by tenants, not owner occupiedThe property value is usually higher than both the UPB and the legal balance, sometimes significantly higher than theNow it is important to mention that I have very little experience with issuing notes and buying performing notes.

The distributor later decided to consolidate warehouses and signed a long term 3N lease for the whole property.  

Can a residential rental be 1031'd to a syndicate or a NNN warehouse?
