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

Give them contact info for a local gym that has drop in fees.

I'd drop the price every week $50-$100 until you get it rented.

Looking at two potential ways to buy real estate for long term hold rental. property A assume the loan on a property with no equity at 6% interest rate.

They are subject to the rates from the lenders they work with. 

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.

The new mortgage on the new $340k duplex home which is an FHA loan is going to be a monthly payment of $2800 and we will refi ASAP (the current rate is 6.7%) when rates go down.We have done some nice improvements on the SFR and will be refinishing the wood floors before a renter moves in (July 1) so feeling like it's a great opportunity for the right long term renter and we plan to screen prospective tenants well.We are taking a $20k HELOC on the SFR for the downpayment and plan to pay that off within 12-18 months.

Texas is a great state to hang up your license and with property values increasing and rates on the edge of a breaking point. 

Granted the terms I offer a lot of the time aren’t amazing (they have very low interest rates), but that’s the only way I can make deals work.

There are some pretty good products out there available for investments, where you can do seller paid temporary rate buydowns.
