This idea is really in the beginning stages so I'm open to all types of scenarios/questions/feedback. - How many units can I fit into this size of a property- Looking for a ballpark range of cost for the investment broken out (zoning, permitting, plans, construction, etc.)Thanks in advance.

They all provide cash flow in different stages.

I can relate to that because in my beginning stage I spent my last 500 on a guru course.

Looks like you are getting ready for the next stage of your investing.Account Closed  is right,  it sounds like you are a good source of knowledge with your current level of success.  

Will you be staging it?

We have 5 kids total, 2 in college, 1 in high school and 2 in elementary school.  

I use a professional to stage all my properties selling retail. (1500-2000)Just some things to consider to budget for when crunching your numbers. 

As someone with a great credit score and history, but self employed for many years, I am limited in the types of financing available at my stage of investing.

My something was being broken into and having copper stolen, having to replace some new drywall and carpeting in my finished basement due to the broken copper, having the furnace go out 3 days before it was getting staged.

I am only at the stage of trying to educate myself. in whole selling right now, but I found a website that says they connect whole sellers with buyers and that they buy properties too.
