The tank size doesnt matter as much as the perk rate of the soil .  10 gallons goes in and it displaces 10 gallons into the drain field .

She came back today with a 7.375 rate and 7.7 APR or 7% with .71 points.

However we would be "getting more house" ( access to a second back yard, tool shed, driveway, second storage unit, etc)When I look at other houses in the area, with the intrest rates as they are, I don't understand why anyone would buy multifamily and rent it out when all of these calculations would be negative cash flow.

Here's a bit more in detail about how rates are calculated for DSCR loans:1.

**PITI is $522 a month (2%interest rate)** Actually cosmetically ready for renters and appears fixed up.On the inspection report the plumbing failed and it mentioned shifting soil in the foundation report. 

For example, if you expect this property to be have a CAP rate of 10 after you repair and it comes time to sell, maybe run your numbers at 11-12 and still see if it would be worth it.

I'm in the position to apply(depending on lender DTI requirement) for conventional financing through the builder at <6% interest rate in this current market.

we purchased the home at a 3% rate and have owned it for about 2 and a half years.

We have a local credit union at 1% origination and 7.25% rate, plenty of good locals at a point and prime plus one, and some good local private lenders. 

How did you get approved to buy this as a single-family if you need roommates, especially with these rates?
