Mainly hoping to get some ideas on the following bullet points:1. how to narrow down geographical locations/what things to keep in mind (ideally can use something like AirDNA)2.

It gave a legal description stating the lot and block number, but can’t seem to find the actual address.I did end up calling but they weren’t able to help me so I’m just wondering if anyone else would know how to find the addresses to those properties.I appreciate any help.

I am looking at purchasing another one of these properties which fits the description above.

I always thought GJ was a prime geographic location in terms of the above.

The property description mentioned one of the units being completely renovated and the pictures of those renovations looked very well done (new stainless steel appliances, cabinets, flooring, as well as a new HVAC), although nothing could be said for the other unit. 

Adding that to your description upon sale and pointing it out to buyers will certainly help and not hurt your efforts to getting top dollar.

I'll write a quick description of each system I considered and why I used or discarded it.The winner:- Xero is what I am plugging forward with (thanks for the recommendation @Gita Faust .) 

Great description.

The only thing is on her website description it mentions that "commercial landlords and tenants value her extensive experience..." and "multi-family housing, including HUD subsidized..etc." but no mention of residential. 

Mike Dymski Very helpful description, thanks.
