Construction estimates are a sum of all of the items to be repaired or replaced, both major and minor.  2 houses side by side may be completely different. 

Unfortunately it does seen like this property is very unique so it would be unlikely that you would be able to comp exactly "like items" in this case. 

It's hard to evaluate the numbers since they don't show a line item break out of the expenses.

Some other items were Diversify investments, and do your homework on the Sponsor.

I didn't want to keep coming back to the site so I created a Google Doc and a Google Form to help speed up the analyzing process.From what I gathered it looks like knowing the following items will help: PURCHASE AND LOANpurchase price, closing cost (2.5%), down payment (20%), annual property value growth (appreciation at 2%), loan amount, interest rate, points charged, and loan term.INCOMEgross monthly incomeMONTHLY EXPENSESproperty taxes, insurance, repairs & maintenance (5%), vacancy (3%), capital expenditures (5%), and management fees (7-10%) From there I calculate the total income, total expenses, and the mortgage.

A couple items to keep in mind when looking: - Only some areas of town allow short term rentals due to the zoning.

The listing shall include the name of the material supplier and/or sub-contractor, amount of payment, payee address , corresponding cost break down line item number.

It is an "equitable right" of EITHER party when damages will not be good enough (inadequate) or the item is unique.

If you update most of the items during the rehab, you should have at least a few years with no/minimal repairs or capex expenses. 

@Ryan LinskeyThis specific item is not common, but service providers can charge itemized fees for pretty much anything if they wish.
