I would be looking at about 50 K loan and can go  upto 12 % interestTo be clear this is only for future ..most probably next year when I start to scale 

And then payoff the home equity loan about less than $60,000 within 2-3 years.Thx.

(the same loan you likely used to buy the now rental and your current primary) There is no reason no to use a conventional loan if you qualify because the rate AND terms will be better with a conventional loan then a DSCR. 

Is there any other loans that I should apply for?

@Rob K. is finally the first person to chime in with my standard answer.

Here is what is being considered:SCENARIO 1):1) Parents loan us money at X% rate.2) Loan terms would allow for early payment without penalty (we would get a conventional loan in 2-5 years to pay parents back). 

We would be looking to use a conventional loan.

Anybody on the LLC or the operating agreement can qualify For the loan. 

You can use a DCSR loan alternatively, or as I love to do; buy homes using seller financing.

Depending on how many you anticipate buying and how quickly may provide insight into whether or not you want the added hassle of finding loans with an LLC.
