You'll notice the areas that do not have rent control are extremely expensive compared to the rent control areas but even rent control locations go through their own rejuvenation process (Santa Monica, Pico-Union, etc). 

Looking to rejuvenate this thread in regards to a Delaware meet up.

However, just like a gear, constant grinding will eventually lead to wear out.Hitting the reset button, when needed, is a great way to rejuvenate your mind, body, and soul.

My only hope is a house so gross nobody will touch it but those are getting to be more and more rare as investors (and homeowners) rejuvenate the area.

I would love to get involved in rejuvenating my former home.

Offering to let the tenant stay at their present rent for the two months will insure you have time to find a new tenant without a vacancy.New owners have a ideal opportunity to raise rents without experiencing any vacancies assuming the place is move in ready, if not one months lost rent to rejuvenate the place after a 9 year tenant is well worth the cost.Send the notice of rent increase and then sit down with them and work out the details if they decide to leave.

Most individuals will not know how to deal with massive foundation/mold/etc damage to their homes and I don't know if they want to spend the money to rejuvenate their home back to a functioning condition. if the home-owners didn't have flood insurance and they choose to walk away from their houses then the banks and city have an issue on their hands because there will be a surplus of damaged homes that can fester mold and other grossness that few will want to put money towards.

I'd also suggest looking for areas of town that are attracting investment and/or undergoing rejuvenation too - Kendall Yards, for example. 

With the knowledge I have, the networking I have done, and my core principle of helping others I really believe that I can not only be successful with money management but also help the rejuvenation of neighborhoods and create happy long lasting relationships with people around me.

However, they could be just starting on the road to rejuvenation and replenishment.
