The numbers are important but you have a look at all the factors especially the market and lending side of the equation.

I cannot argue with a straight face that the market value fluctuates monthly and equates the actual monthly collection.The overall idea of using an S-corp to control SE tax is valid, but it needs to be implemented differently. 

I have a set of essential equations to evaluate deals before entertaining further analysis. 

The bank views a year lease as less risk for them and a form of stability which as investors we know doesn’t equate to security in the real world .

Are there any other holding costs that needs to be put into the equation? 

If you factor in principal payments in the equation, I'd be looking at $338/mo as of right now.On the flip side, I'm pretty sure on a conservative estimate, we could sell our home at 175k, possibly as much 185k.

This is the reason why I'm having a tough time figuring out how to move forwards and be able to properly analyze deals since the rehab estimate is such a critical part of the equation and I don't want to just be shooting in the dark.

This is another example where the population (10 units) average ($500/unit) does not equate to the individual unit cost.

Changing to Craigslist could result in more vacancy or possibly lower nightly rate which would equate to loss of income. 

Also, I was overlooking the short term capital part of the equation and that makes sense.
