I think it depends on the layout.

Even then it would only be one or two units to get a feel of the condition and layout.

I have downloaded several real estate books on my phone and skipped to this chapter but they don't seem to layout the mechanics of the paperwork in a way that it protects the buyer and seller.

The project took about 2 months as I fired 2 different GC's until I finally got one who followed instructions and had good judgement/intuition/quality of work.

I'm meeting with my real estate attorney next week to lay out the plan.

Relationship with a process may seem counter intuitive but the process is what's different in different locations.

I'm just not sure what to install and/change about layout or design features (like spindles on a railing, or the front facade of the house, etc.) to make them look more updated.  

Perhaps  I will make it available someday for review by a select few so that they may incorporate some of the layout, ideas, and features needed to get a bigger deal consummated. 

I think it's a great idea and you should follow your intuition on this- those added benefits like you mentioned will definitely be welcomed.

With the investor, you might want to use some of the tools here on BP to lay out a professionally developed plan and show them that they could earn an attractive return if they were willing to carry the property.
