For insurance it can depend on location, how old the house is, what the construction of the house is, if you plan on getting full rebuild or just enough coverage to cover the debt service.

  ( if it was not obvious the line had been replaced in the recent past or was not PVC.).Its one thing I see many turn key buyers miss in their home inspections is a sewer scope.. out in our market every realtor first thing they do is recommend a sewer scope I even have them do them on my new construction homes..  

An investor in your area that does new construction should give you some ideas. i would also Google it.

You're never too young to start :) my first deal was at 18, New construction flip of a quadraplex.

I'm in San Jose working with a youth corps programs that is starting to do Tiny Home construction and we are reviewing all the regs etc for California -- the hope/goal is to make quality homes to service our homeless population then the community then eventually FEMA etc...These will be on trailers - Our approach will be to approach members in the community who would like to have the extra rental income by having on elf these on their property -- no doubt there's a lot of hurdles ahead of us but we have a record of building/construction - the challenge will be the market and regulations  which I guess always is the case....

However, lenders construct second mortgages as either home equity lines-of-credit (HELOCs) or shorter term, higher interest rate, full disbursement mortgages for homes.When selling a home, a second mortgage, regardless of the homeowner's use of the funds, reduces the seller's cash received at the closing of the sale.

That will tell you what type of construction the specific industrial zoning will allow.

I‘m Open to all constructive criticism and advice as this is my first property.

The listing says pier and beam construction, not slab. 

Personal friend is wanting to come stay in our area and learn a little construction.
