Got a number of deals rolling (now pure flips, fixers, and a number of rentals) when we got orders back to the UK. 

At 4k a month in rent, you'll be lucky to make $100 a month.For a flip, you wanna make sure, you can sell it for 30% over purchase price, so 450k after holding for 6 to 12 months.If its long-term hold and wait (hope) for appreciation, then it would be pure speculation.

I was looking for advice from someone who has experience with pure land lots, I would like to know what to look for, what to avoid, and other details like that.

The closer to the water the better. 

This is an easy way to get started, test the water and learn the basics.

What is the process on getting a C.O.Also there is 1 heating and water bill for the whole building.

We now own 90+ water heaters(or units of sfrs and apartments).

Not all lenders track guideline changes.Most lenders base their knowledge around water cooler chit-chat, which is disappointing but true.Classic Example: The Americans with Disabilities Act, and presumably the corresponding mortgage guideline changes, was like 25 freaking years ago, but I still had an older coworker shocked and assume fraud when I did a loan for a guy on temporary disability.

So even though I didn't quite have the numbers where they needed to be, I made the leap anyway knowing that it was up to me to make it happen, hell or high water.

The worst thing is that we really get very few services for our taxes, i.e. no city water, i have a septic system on my property.
