I used LLCs for active businesses to keep entities separate from other businesses to insulate one business from another in the operation of unemployment insurance, workman's comp insurance etc.

To start you have lots of potential issues like asbestos and lead paint, old wiring and plumbing, lack of insulation and inefficient windows to name a few.

I've come across a few interesting ones, but they are built in the 1950's, 40's and 30's.I know some of the things that I need to consider in these older properties when deciding what price to offer is potentially upgrading the plumbing, electrical, insulation, etc.So I wanted to get some feedback on how to get a sense on how to estimate the costs to repair plumbing and electrical?

Is insulation and vapor barrier necessary?

So you may need permits, plumbing, electrical, insulation, sheetrock and painting to get the place to the usual "empty house" status.

Do prefer to buy newer properties, built say post 2000 where windows are double glazed, modern insulation etc... 4.

And some of our modern day necessities were after thoughts especially AC and insulation.

Think new windows and R-19 wall insulation, R-50 ceiling insulation.
