Who is their architect for all plans and permitting?

I am planning to build a portfolio dashboard for my properties in Excel, and I have a pretty good idea of what I want to see about them individually and combined. 

I'd talk to your broker on what it'll sell for after the fact and where the market is heading over the time you plan to own it. 

@Matthew Posteraro That's a solid plan.

NYC laws around rentals—especially short- to mid-term—can be tricky, so you’ll want to avoid any compliance headaches.The biggest challenge with this plan is finding a rent-stabilized apartment that makes financial sense and actually gives you breathing room.

Many people choose NOT to have this, because the administrator will then vet every investment you make to ensure you do not invalidate your IRA.Invalidating your IRA means that you've done a prohibited transaction and the entire account is then deemed as distributed to you.If you don't want checkbook control, then I recommend a plan administrator such as Equity Trust - www.trustetc.comIf you are sure that you're aware of all the rules around prohibited transactions and disqualified people (who you can and can't do business with), then a plan administrator like Sense Financial would be a good place to start talking.

That being said my residential rental will have a positive cash flow of $500 and I plan to rent out this other side of the duplex immediately and will have a balance of 600 to cover for the mortgage.

Hoping for a resurrection with deregulation & any yet to be announced plans for DC….

Plan to buy at 4 duplex and a single family(which includes a lot) this year.
