So any good methods anyone?

Greenway insurance came in at around $600 for our 130k duplex in Galveston, structure only.

Planning new construction and the Architect gave me a quote for $4,500 and Structural Engineer $,3000.

Your numbers will likely be better if you continue the room by room method, but it will just take a bit more work. 2.Be sure whenever you get the property to get a lease that is specific to room by room leasing.

One of the nice things about seller financing is that sellers and buyers have broad flexibility in creating a win-win.Many seller financing sales use 5-10 year balloons so if your friend, the seller, wants a structure where he gets paid off in a time frame less than 30yrs, you certainly have the option to buy it with a balloon loan from the seller and than sell it with a baloon loan to a buyer.   

I would suggest you do a search for a local structural engineer in your community.

I'm approaching this whole project as a big learning opportunity, to develop a skill-set I can use for future projects.I have a lot of fun plans for the garage of this property, which is huge, insulated, and has a bonus room, as well as a good structure for a garage-top deck. 

Possibly even AAGLA or another local trade org.I'm under the impression that if the parking was included in the original lease, you can NOT separate that amenity for existing RSO tenants, but, for new tenants you can structure the lease so that the parking is it's own separate lease, and that parking lease is not subject to rent control.  

One of that is to elect slower depreciation method.
