I understand that it may take time to build the capital for larger deals, but I’m committed to making it happen.

Sean,I have had some good exposure to larger commercial/industrial deals but would like to start investing on my own for small multi family properties, ultimately end goal is to build a portfolio that can someday support my retirement, provide flexibility for my family, and create something that I can work on with my kids to show them the power of real estate and entrepreneurship and hopefully someday pass down to them. 

But they are not very popular and usually for larger properties.

Here’s how you can leverage it:Upgrade Your Property While Deferring Taxes: By using a 1031 exchange, you can sell a current property and reinvest the proceeds into a larger or better-located multi-family unit.

My question is should I take the money I have and pay off the Heloc and then when everything is sorted out borrow the money for the building, or just keep making payments and wait it out?

However, let's say the lender were to foreclose on an existing PadSplit, what has a larger buyer pool: (since any lender that want's to foreclose wants to make the disposition of property as seamless as possible), a standard SFR, or an SFR with multiple modified bedrooms/faux walls?

This can include coordinating around tax strategies, estate planning, and cash flow management—all while considering your real estate portfolio as part of your larger financial picture.

Doesn't this hurt the tenants trying to move to a better location or larger home for their family? 

I find with larger homes that are big enough for wedding parties, reunions etc that I get a lot of bookings well in advance, with ~50% occupancy several months in advance.
