We have found that in our area Cyberhomes is usually fairly accurate, but you can not take that as gospel, since they do not necessarily use like COMPs all the time in their formula.Once we have all of the COMPs in a 1 mile radius over the last 3 months, we average them, subtract what we feel repairs will cost, then multiply that by 70%.

All this, when federal workers are multiplying like bunnies!

After selling this property i'll be armed with about 240k in cash to go out and find a DEAL on another property.I told myself the next property I buy I would not pay more than about a 72 gross rent multiplier.

These are retail values, so you would want to probably multiply these by .60 or so to see what a wholesaler might offer.

Multiply that times the number of deals you do a year.

Here the data:Purchase Price $54,750.00Total Annual Income $34,200.00Total Annual Expenses $20,726.00Down Payment Amount $5,475.00Percent Interest Rate 7.50 %Total Mortage Term (years) 15all Utilites paid by tenants, only common electric and water by ownerneeds $15k for repairs, 6 units with one vacant unit actual, annual income is for fully rented buildingI run this on iAnalyze and received this:Gross Rent Multiplier (GRM) 1.60Net Rent Multiplier (NRM) 4.06 Operating Expenses Ratio (OER) 60.60 % Debt Service Coverage Ratio (DSCR) 2.46 Break Even Ratio (BER) 76.63 % Capitalization Rate (Cap.

The debt financed fraction (0.67, roughly) is multiplied by my share of the income and that amount is subject to UBIT.

That is:{(Monthly Income) minus(PITI+10% of mo/rent for vacancy+10% of mo/rent for repairs)} minus (Repairs needed to get it in good shape) Then I use a 50 multiplier which gives a rough estimate of the 50% rule.

You then get the total interest paid by multiplying the payment by the term and subtracting the financed amount.You're missing a key parameter, which is the length of the loan.

Gross rent multiplier of 4.8.
