I'm torn because people say "don't sell... houses are going to keep going up".

But I don't want to waste other people's time and would definitely feel a lot more confident overall if I knew that the money was there. 

I need to make my first move so as to avoid analysis paralysis but I don't know how to go about it.I hope to meet a mentor(s) who can help me with my vision to own numerous single and multi family rentals to create cash flow, financial freedom, and a legacy for my family.

Yes development can have huge upside but I have also seen people lose $20M in a development deal gone bad. 

Looking at this kitchen (Rehab/Flip deal), I know how to price out work and deal with subs but how are people coming up with how to redesign the layout?

I learned that April and May are seasonally slow for rentals, since most people seem to move in the summer, and also that the market here in Wesley Chapel, FL is a bit saturated with excess inventory from all the new construction activities in the area.Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

You seem pumped up to do this, but do it first at a local meetup (in terms of connecting with people) or else you are just going to get a bunch of people trying to sell you services or on how good they are.

To fill a vacant mobile home park lot typically requires bringing in a home and selling it, while filling a vacant RV park lot simply means somebody pulls in their motorhome or travel trailer.Think of RV parks more like owning a restaurant (and the hands-on management that entails) while owning a mobile home park is more like owning a parking lot that rents spaces out monthly and is much more passive in management.Some people just prefer one business model over the other.

More importantly, there no great bargains there…people are paying at or close to market value.
