In the above example you're dividing the cashflow by 50%.Instead we should be taking the gross rents of 3900 X 50% = 1950 - principal/interest = net cash flow per monththe 50% is to account for prop mgmt, capx, utilities, repairs, and etc

Account Closed the only thing I usually see in properties you are talking about is that they are so poorly divided.

Then they divide that among the non-metered in that area, and then average it out and bill you accordingly.

Divide the 20% down payment you did not have when you bought your house by the monthly PMI payment.  

So, divide that by homes/appartments or whatever and that's my number. 

I'm fairly sure given the inversion of the partial differentials between the CPI and Libor rates over odd years we see what the discrepancies between that which the inflationary Markov chain indicates compared to normal stochastic methods used to define the tangential M3 money supply divided across Ricardian land scarcity.

If our final investment is 85 which it looks like it will be, and we rent for 1250x12=15k - 2200 for capex, expenses, insurance, and taxes, that leaves $12,800 divided by 85k = 15% ROI.

If all you are doing is dividing made up NOI's by made up asking prices then you do not get a number that makes any sense. 

If you can get the annual rents, divide by 2 to get a decent estimate of NOI, then divide by the purchase price to get Cap Rate (actually, add the cost to cure any must-do deferred maintenance to the purchase price first so that you're total investment is factored into the Cap Rate calc).

@Forrest ShealySorry for late reply, didn't see your question.To get a rough estimate for the rent to value ratio, just look up the average rents and divide by the average home/sale price.
