I know the way to figuring that out is being able to read the numbers and factor the correct range of the estimated repair cost.

when it comes to monthly cash flow I ask myself the following question: how much money would I need to make per month to justify taking on the added responsibility of dealing with this property. for me that answer is $250 per unit cash flow, after all expenses and accounting for repairs/capex.

I can also mark down what addresses need cleaning or repairs.

In the down turn cycle there were almost no new builds and lot's of foreclosures and short sales which required lots of adjustments and repair estimates.125-150 is typically a full interior BPO where they take pics inside and outside of the property.

Lots of repairs.

That's including vacancy, capex, repairs etc... in both figures.

I recently purchased a house in Woodstock, IL, that is in need of some minor work (repair exterior 2 story wood stair, replace dryer gas line, replace old window casements, etc.).

Contact a broker or look in Scotsman Guide to find an appropriate lender.Check your costs on the bridge loan to see if you aren't better getting a fixed loan on the free and clear property and adding an equity line of credit after repairs are complete or refinance. 

Your realtor will run comparables of other similar homes in the area to see how much you should really pay, and will go to bat for you to negotiate repairs, closing costs, etc to get the best deal possible.
