There’s an electrical supply company that lists stuff on EBay and the cost was 1/3 what it would have been from our local electrical supply company.

Feel free to reach out if we might be able to help with anything there.

You can find plenty of people willing to share information for free.

I estimated that my repair costs would be around 25k. 

If the attorney recommends a set up that involves more than one LLC, get on the phone with your tax person and find out how much that is going to cost you for the tax returns, K 1 forms, payroll processing, etc...

Or is it considered a price reduction, lowering your cost basis in the property?

RentRedi and other similar services can help manage applications, leases, and maintenance requests in one place.

I'll handle rehab cost, management and yearly expenses etc...and would like to build a nation wide company consisting of low income-luxury buy and holds, fix and flips, commercial, development and eventually branch out to vacation rentals as well.  

In addition low cost markets do not add much value for rehabs.  

Feel free to reach out if you have any questions!
