I'm aiming to convert the 4 unit building to a Co-living building.

It's best if your clients go there with the measurements of the kitchen area - nothing fancy, just something plotted or hand written out on a piece of paper so they get an accurate price estimate. 

It's not the one that draws the fastest; it's the one that keeps their cool and aims the best.Be smart, not fast.

The property is walking distance to the PATH train (subway) into lower Manhattan, so rent rates are increasing and we aim to appeal to high earning tenants.

You are trying to measure it in dollars.

I aim at renting until next summer so I can know the area + market better before hopefully purchasing there. 

I usually find out what the setback is and then with a long tape measure and a metal detector can usually find property corner markers.

Aim for the cheap/ugly houses with bad roofs in the C/C+/B class neighborhoods and hit the ground the running.

If you're aiming for a conventional loan on this investment property, the lowest down payment allowed is 15%, and that's likely going to come at a cost in points, so I worry you wouldn't be retaining that much in the end.
