. $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?

Estimates are bout 400k for full gut remodel (hvac, plumbing, electrical, roof, mostly new windows, kitchens, and baths, minor re-framing) New plan is for (2) 2B1B units and will rent for 2k and 2500/mo. 1 unit is a larger 2 bedroom.

It is mostly families in our larger units so not much in the way of problems, but there is a bad apple here and there. 

If the spread was larger then the amount of time involved might be worth it.It's always time versus return, risk to capital, and how hard you have to work for it.        

.- While MTRs can be any size property, the bedroom/bathroom count is really important, especially with larger properties.

It's not likely your friend was saying that you would get another HELOC to go in 2nd position (banks don't like to do a HELOC behind another HELOC).My guess is he's saying you get another HELOC with a larger available balance, and use that HELOC to payoff whatever is remaining on your existing HELOC.

You have to purchase a larger single family homes, 6+ bedrooms.

Add walk in closet & larger master bath.

I’m curious if these are isolated trends or part of a larger pattern.Looking forward to hearing your insights and experiences.

However, the property I'm looking at is larger than other houses, and to make it a viable investment, I'd need to rent it out for about $2,600 per month.My concern is that anyone renting this property could instead take out a mortgage on the same house, with monthly payments exceeding $2,000.
