There's a fundamental mathematical principle at play here as I noted in my previous post.All that said, if you continue doing what you're, your loans will be paid off quicker--so have at it. 

These neighborhoods have had favorable zoning for a number of years and development usually follows the path of least resistance.Keep in mind prohibitive zoning is a leading barrier of entry and is usually why neighborhoods lack new supply even when the underlying fundamentals and demand are strong. 

Are employers moving in, is the population growing, is the average household income high, does it have good market fundamentals?

I was not in the industry at the time, so I am not exactly sure who that 3rd party was, but I would say there is recourse if the appraisal is fundamentally flawed.

Based on the knowledge I have of the neighborhoods fundamentals and trajectory, will the most likely buyer still be an investor 5 years from now?

Investor buys in a  market that has poor fundamentals and is stagnant.

@James Kiefer From what I understand Pittsburgh happens to have some decent underlying fundamentals so it may not be a bad place to invest but certainly speak with local experts.

You should be placing far greater emphasis on the  fundamentals of the neighborhoods in which you invest.

There is fundamentally zero need for a bank to entertain a bid on an NPN from street level investor.  

Also I want to add few things.Structuracally there's fundamental very wrong in PRIVATE EQUITY/PRIVATE INVESTMENTS in CRE ( well almost in anything):- From realized investment, track record even the sophisticated operator is questinable, you can't just keep selling 5.2 cap to 4.8 cap and expect this to be continued, it is just impossible- Multifamily syndication CANT survive if financing aspect is only 5 year baloon, it has to be 10-12 years at least.
