I will mention that a hot tub could really increase the frequency of bookings. 

Most owners are local and therefore “hot” money or out of area players are not yet chasing Pittsburgh assets, keeping prices favorable.References United States Census Bureauhttp://www.cmu.edu/news/stories/archives/2017/august/economic-impact-report.htmlMarcus & Millichap 2017 Multifamily Investment Forecast2017 Commercial Real Estate Trends Report by Integra Realty Resourceshttp://www.pittsburghmagazine.com/Pittsburgh-Magazine/September-2017/Staying-CMU-All-Eyes-on-Carnegie-Mellons-Future/http://www.nextpittsburgh.com/features/pittsburgh-developments-watch-2017/

You could do it your way but I’d recommend a bit of a hybrid model.

I worked for a bar company and we went around grabbing beat up spaces and turning them into hot nightclubs. 

I remember studying your business model early on through your posts and early podcast episodes.

Having used both, I would go with propstream if you're looking for a solid data platform, and are investing significant money into other systems as part of your business and its growth model.

Also given the slow market it seems some RE agents are willing to consider a hybrid model.

I would not characterize this as a scam per se.. but it appears to me to be a failed investment model..

Chosen right, some of those South side neighborhoods may become hot, and give you large amounts (percentage-wise) of appreciation.

Travelers, Farmers, Steadily are some who allow this model.
