These costs are generally not something you can get increased cash flow for, nor recoup.

I don't have info yet on HVAC, plumbing, roof condition. 

FORECLOSURE: A seven year waiting period is required, and is measured from the completion date of the foreclosure.A three year waiting period is permitted if extenuating circumstances [EC: non recurring events that are beyond control that result in a sudden, significant and prolonged reduction in income or a catastrophic increase in financial obligations]  can be documented and the lesser LTV of 90% or the standard product guidelines.

This significantly increases the premiums and I'm not sure its worth it.

Since I doubled the income does it increase the value of the property? 

Lenders that sell their loans today are also taking part in what they call CMBS 2.0 (post 2007 underwriting criteria, where it is very common to see certain terms and conditions implemented for the additional security of the bondholders, and the increased risk of the Borrower (you)).The one thing that I see over and over – even with some of the biggest players in the market, is this: Investors spend a lot of time and attention on the due diligence of the property, economics affecting property performance, property management, repositioning, and on closing the loan - - and NOT AS MUCH ATTENTION IS USED TO PREPARE FOR THIS ENTRY INTO THE FINANCIAL MARKETS, (WHERE THEY WILL BE RESIDING FOR UP TO TEN YEARS) AND HOW IT CAN ADVERSELY AFFECT THEIR RETURNS.

Your not going to find a nice move in condition home on the MLS with an agent for $30k.

I then calculate my All-in cost basis (Purchase price, Rehab costs, Holding and Closing costs) using the LTV ratio the lender provides.If it still looks good after the analysis I will visit the property to get an idea of the condition (taking pictures).  

We bought a house in fair condition, which most people would consider a teardown in my area.  

Going thru the building I'd say its in no worse than average condition, for this demographic the units will work fine.
