We did find a place for 350k in San Diego once - come to find out it was half burned down, literally!

Also, installing windows means you will have to get a structural engineer to see if a bigger window can handle the load, especially if you have a brick building.

The newer models are fine, they eventually required manufacturors to build them according to house codes, so enter drywall, roofs that are not rolled metal, better wiring, escape windows, exterior doors that were not tin covered paneling.I have been in several mobile homes that were burning. 

I’m looking to reverse engineer my operation as I believe is the smartest way to building a successful business model in this realm.

(FYI - "Local service business lead generation" is in regards to search engine marketing for businesses connecting with clients, not in regards to investors finding property leads.

No matter how much it burns you up inside.

@Lee Burns sounds good

It would be really difficult to get sound advice without consulting a civil engineer in depth about both the subdivision and permitting a new building on the land, they could run you through the process and costs with some level of accuracy. 

When it burns your tenants will sue you and will probably win.$8k seems high for a service upgrade, but I'm guessing that also included replacing all the sub-panels in addition to the main.
