I realize I'm totally in the minority here, but just wanted to drop some "food for thought".

I understand you are taking care of their property, keeping it stocked with food items, toiletries and fresh linens.

They would likely be attracted to an area where there are trendy restaurants, coffee bars and organic food grocers. 

That 220 million dollar project by Tyson Foods could have been about 10 miles from my house. 

This is providing all egress and safety codes were met.

Well...the Dayton Dragons baseball team has the most consistent sold out games of any sporting team in North America (startling fact), Warped Wing opened a second location, and a half dozen other breweries are now open in the city...Boston Stoker coffee is totally awesome and has several new locations (this is important because it's a key indicator for the successful revitalization of many cities...beer-food-coffee is key)...there is a river front development that is reminiscent of Columbus (which was awarded best on the country), there is big inner-city revitalization...I saw a developer by the name of Simms pre-sell 24 $500k "Brownstone" townhouses in the center of downtown (unheard of in Dayton)...there are 30 renovation projects going on downtown...and they now have a full time staff on the streets to keep the city clean...the population is on the increase for the first time since 1964....I mean this is pretty superficial, but it's every bit as important as economic indicators...there is a lot more to this...There are still "war zones" in abundance in Dayton and it's the Opiate Overdose capital of the USA...but getting better rapidly...just proceed with caution if you elect to invest there...a local subject matter expert is a must!

Pigtown has some incentives associated with it from some local companies such as UMMC however I really see this area taking awhile to develop and some of the people I know who have purchased there regret it due to safety issues. 

My biggest concern is not having enough of a safety net for that second purchase. 

The equity in the home is the only safety net you have to buffer what will be negative cash flow long term.

@Bosko MijatovicQuick food for thought ... you may need to really go off market if you need that deep of a discount.
