My numbers are almost the same as yours, except the price and rents are multiplied by just about 3X, with slightly higher square footage.

Gross rent multipliers.

Found the average price per sf, and multiplied it by my subject house sf.

So if you figure your area and convert to yards, multiply by 500 and divide by 2000 will give you tonnage also.If you're needing a base you can use a geo textile if you do not want to buy #2 stone (big rock, 2 to 3").

That is $90K FMV less the $15K repairs multiplied times 70%. 

At least, that is how I count it.Once you multiply the ARV by the 70% you subtract the cost of rehab.

At some point the re-leveraging of the balance sheet - remember more cash on the balance sheet but even morerer debt (as we noted here) - requires risk premia that outweigh even the biggest avalanche of yield-chasing free money.

@Chris Friberg  I'm actually curious if banks will lend on multiply types of loans like this.  

Rates are annual, so to calculate interest, take the outstanding loan amount, multiply by 14.5% and divide by 12 for the monthly payment, or since the amount of outstanding interest will vary as the loan disbursements increase, you can take the outstanding balance, multiply by 14.5% and divide by 365.
