For a first time investor, I definitely recommend house hacking for most people as homeowner loans are by far the best in terms of rate and LTV. 

Yea they would keep that in place and you'd get a second position mortgage for the rest at, well, higher than todays rates.

You have to compare your expenses with each management style and find the option that works best for you.

It's free to sign up for an account and the savings account has a very competitive interest rate.

I also wouldnt let your mom go into 2nd position on an investment property with any sort of restructuring; it doenst sound like she's in a position to risk being wiped out.Overall, though, if you want cashflow on the new property but cant achieve that after a refi into a market rate loan, it probably makes more sense to just flip it, pay off your heloc and your mom, and use the remaining capital for the next deal.

If you're hesitant to take on a long-term loan do the 15 yr. loan in your name because you'll get a best rate.  

While rates can be higher, they are efficient for temporary needs.2.

Quote from @Dinesh Nair: I am a Canadian investor with a US corporate entity- we closed on our first property and now working to find financing through a lender… however rates keep changing all the time.. is there a site to track rates ? 

DSCR recently came popular in the loan brokerage and private credit space with the rise of STRs and MTRs.Your local bank lenders will have the best rates typically.  

In the end, it is viewer’s choice to follow what they think is more reasonable.
