A couple things to consider:The infrastructure was designed to support a specific development (number of parcels, certain square footage and/or water consumption). 

I have a good network but I feel it could be better, Im in a hot market but the wholesalers are starting to really make alot of money without touching the properties and I feel I got the DIY experience I was looking for so Im now writing my own letters and about to start mailing them out today and Ive also looked into some online back office autopilot software that claims to generate leads for a monthly fee.

Kids are unbelievably disorganized and trying to get them to do everything they need to do to have cable, water, electricity and pay YOU on time is asking a lot!

I feel like flipping during this hot market and then purchasing buy and holds when the market dumps would be a good idea.

me personally I would never buy a park on private sewer and water.. again personally I would not do this. too much risk.

I'm trying hard to find some things that work in a hot market, and the $300 -$400/m in interest on the DP loan is making it tough to hit cash flow targets.

You have many options.I don't know what rental prices are in Houston, but I have very many friends and previous buyers who have paid $1,200 a month for 800sqft-900sqft units (with water being the only utility paid for).I recommend West Gate area.

That being said, I think I still have a ton to learn about the Short term industryOne area that keeps popping up as a hot market right now is TN, (gatlinburg / pigeon forge) which I am starting to look into. 

What are the hot, upcoming areas in Philly?!..

And its not really the snow that causes problems its the water from the snow melting and ice from that snow melt then re-freezing that is the biggest issue.
