Doing it this way will allow me to qualify for one of my other rental properties and assume the mortgage at the existing 3% (DTI issue) 

We use an online payment system and we only allow one tenant to be responsible for signing up to make the monthly payments.

In theory I can assume I both mortgages without refinancing which would be ideal.

If I got a Heloc, once the property is built, could I get a traditional mortgage and pay off the heloc and then tap into the new equity as well?

Hey @Alex Ferranti, Trust me, you are not struggling; it's just not as easy as it sounds or as gurus portray it online.

Most banks and traditional mortgages "Do not" allow foe the property to be vested or quit claimed into an LLC unless it specifically states it on the closing disclosures.In most cases even on DSCR loans the Bank/Lender still requires you to sing a personal guarantee even if they allow the loan to be vested into the LLC.  

You need to have a first mortgage, however, to do a HELOC on a property. 

However, the investor owes more on the mortgage than the properties are currently worth.

The most obvious is that you will be able to offset your mortgage with renting out a few rooms.

I'm sure there's also a ton of information online or on Youtube about each of these asset classes you could take advantage of.
