If you decide to sell and find an investment property with a greater cash flow potential.A 1031 exchange would allow you to indefinitely all of the tax and use it to your advantage to reinvest into larger nicer property/properties.

Without accounting for management fees (I have not yet decided if I will try to self manage), and with planning to raise rents to typical market of $825 for each of the smaller units, and $1200 for the larger unit, does this seem like a worthy first investment? 

Leverage magnifies return. 3) The effort involved in adding an ADU is comparable or larger than a rehab associated with a BRRRR.

What I've realized is that a lot of these companies that do pay for housing stay in the larger apartment complexes because the companies pay for it.

I've had them long enough to keep pushing up rents so that I am at the top of my niche, but know not to exceed it because I'm just about at the point where if I raised rents another $50-$100 I'd be crossing over into the lower end for larger units.

When I said size doesn't matter as much I meant for STR you don't need massive rooms, larger common areas, etc.If you went MTR you might go further away from RTP and go for higher bedroom count, for less appreciation on average.NOTHING about this post is gospel.

I used to be a landlord and flipper in New Zealand until a couple of years ago when I liquidated my portfolio and moved out here to Pittsburgh.

From what I read and understand, this means I'm likely going to struggle with getting a loan, not even considering the inability to pay any down payment.On the other hand, my parents have significant liquid assets, (think on the order of > 500k), that they are potentially looking to diversify into real estate.

We're in the process of liquidating our Ontario portfolio, which consists of four properties.

Would it be buying more of the same type of properties or expanding into larger properties?
