Also, the tax assessed value and what the house last sold for should not really factor into the equation at all.

Dont forget to factor cap ex and delay maintenance into the equation I see this bite alot of people.

The bottom line is you need to finish the equation and know your acquisition cost (80k), rehab expense (20k) and the after repair value (ARV...130k as an example).  

Often times properties are priced right, so your equation goes out the window.

What you're actually doing is erasing the profit from the equation.

You can find when the subdivision was platted and when each lot was sold and each home was sold through title work, but I usually just drive trough and I can tell about when a home was built and how the neighborhood was established, but it doesn't equate to any profit on a single property.You may be looking forinteresting but useless data, maybe that is why it's hard to find......

The onsite management is pressured by their bosses to have low vacancy numbers even though it has equated to less revenue.

That being the case, your ~$50K equates to ~$3K in monthly take home pay.

I thing that pretty much answers my question.I looked at an amortization calculator and compared the differences and it would equate to them spending about the same amount each month.Unless...

Would I just build the expense of the loan into my "do it or not" equation?
