Possible that some of the property is wetland, or the minimum lot size in your area is very large. 

If you make 100k a yr in profit, then states w no income taxes is your best bet.

What would you say is the maximum amount of units you could possibly build on a 9,910 square foot lot? Thank you in advance

I think you may want to start with the size of the asset you're looking to buy (10 unit buliding, 50 unit, 150+ unit) and the capital you have for purchase.  

I think with a community the size you're talking about, all 2BRs is fine!  

There is no "Popular Guru" teaching lease-option to buy programs where the transactions will be compliant as intended meeting new accounting requirements (by everyone in business) and/or the IRS Code, they don't event touch the subject matter I'd bet on it. 

I am down in the panhandle , the warm banana belt of the state (raining like crazy now) but I like that, like our large state, you have Alaska sized goals..

I would think that Montgomery would be a safe bet due to the military base being there.

When you're just starting out, your opinions are skewed because of  small sample size. 

It's unique in size and structure for the area.How much time and money would it take to get this changed to a legal 4plex, if at all possible?
