The home I’ve been renting is going to be put on the market.

Do I raise the rent and make $600 a month on passive income, keep the property and chance this home not appreciating much more bc of what's currently happening in Florida with excess amount of inventory sitting there?

I have a lot in colorado that I'm interested in builder a spec home on.

But finding such a loan on a primary home would be extremely challenging. 

I have brokers in various states where vacation homes run into deductible issues, HOA reserve issues, litigation, just to name a few examples.

It could be Crazy Investor Loans - giving loans on investment Real Estate packaged by Wall Street (think about the Stupid Loans they gave to Home Owners - So why not Stupid Loans to Investors eventually - just a thought. 

So I have a friend who has taken some serious steps to develop a subdivision: 100+ home sites and a few commercial properties on about 50 acres.

What are some tips that you would suggest?

There is low inventory everywhere and regular home buyers are buying the homes to flip, pushing the prices way up.

Preliminarily, I have looked at Spindell Homes, but not sure if they would build a fourplex.
