I got a verbal offer from another job, so if i start working there, I will have had no gaps in my employment.  

Construction employment dropped by 1,300 jobs in the past year, a 2.8% decline.Construction had been an engine for job growth in Northeast Florida as the economy recovered from the financial crisis a decade ago.

But any 401Ks from old employers, IRAs etc... you can.

May I ask what strategies are you employing in Trenton and how did you finance those deals?

In addition to evaluating the city job growth, you need to pay attention to any major industry or employer that may be responsible for more than 25% of the market, because if the dominant industry or employer is in trouble so is your property (due to layoffs).

I require applicants to have a minimum 2 year employment relation with one employer.

I am also thinking may be to reach out to my neighboring owners and see who wants to buy it when I get it full or at least when I hits 80%, I can take few employees I have with me and go build more (I like being a contractor and not an employer).

Unless some of the major employers move out of Lou. and the local industry can not sustain, you still will have some steam left.

I run into a problem  with lenders being self employed. 

@Kai Van Leuven my pension and 401k are not speculative and several added benefits from decreasing my present tax liability to employer contribution.
