They appear as second loans and need to be illuminated if you need to HELOC or cash out Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

Personally, I'd get a HELOC on it now while you live there and hold as a rental, hiring a solid PM to take care of it after I move.

How would that work with money coming from a HELOC?

I just started to look at HELOC's, and don't think it'll be worth it to refinance because my low interest rate.

You also have multiple equity positions available for future use through a Heloc or cash out refinance.

If you're living there and built up some equity, a possible HELOC may work.

My family has a chunk of unused HELOC; would it be a smart move to use the HELOC to buy in cash and then pursue an SBA loan after owning it? 

Of course financing could be tricky unless you have some equity, in which case a HELOC or refinance might be an option. 

Using SFH primary residence with a HELOC (ex. $425k) to purchase a 12-unit Apartment ($1.5M) with 25% down ($375k from the HELOC).The remaining $50k from the HELOC could go into fixing/rehab of the 12-units.Then cash-refinance the larger amount from the 12-units to pay off the HELOC in one lump-sum (as much as possible), then using the cash flow from the apartment to pay off the rest of the HELOC.Repeat the process with a new apartment.1) Does this make sense? 

If so, it seems like having a few DSCR loans would make it difficult to qualify for a Heloc on a primary residence or even a car loan, for example.
