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

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.

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. 

Glad to see this thread pop up, I was just looking for more info on SFR to assisted living conversions myself...Is there a good source of beginner info on where to start down this path?

Together, we can speed up the conversion process and achieve our goals.

and as for rate its market.

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

Every dollar into this project is borrowed at various interest rates.

Sure you can sell it and take that cash and put it into something that you can manage yourself, but with an interest rate as low as you have it for, I would not.
