I've been looking at buying RV Parks, Boat Marines and or Mobilome parks, I've read that SBA and HUD do have loan programs in these areas.My question is who do I contact to help get the ball rolling and pre-qualification. 

both, I am an expert with several govt programs, 

HOWEVER, for most investment property cash out programs you will be capped at 75% loan to value (the delayed financing piece does  not effect this loan to value max).

Those points have now come down so we're seeing more folks in az using that program to buy from out of state.   

Installation Costs and IncentivesAverage Cost: Residential solar systems typically cost between $15,000 to $25,000 before incentives for a 6kW system (suitable for an average home).Incentives: Illinois offers substantial incentives, including:Federal Tax Credit: A 30% federal tax credit applies to system costs.Illinois Shines Program: Provides Solar Renewable Energy Credits (SRECs) that homeowners can sell for additional income.Net Metering: You’ll receive credits for any excess energy your system produces, reducing your utility bill.2.

If you or anyone here can put close to $500 down and give me a certain percentage on a couple of deals you do I could give you access to the whole program. 

Provide a bunch of free trades programs, mentorships, networks. 

A tip: While comparing mortgage brokers, don’t forget to ask them about any incentives or first-time homebuyer programs that may be available in your area.

Consider financing options like FHA loans, conventional loans, Texas State and Local Programs, and HELOC.

If so, perhaps it is programmed to change temperature on a schedule and they don't understand how to change that.
