This is the first time I've heard of such a thing as a land swap, especially between a municipality and a private entity.

I wouldn't bet my life on 50%, but I would bet they are more problematic than the typical long-term renter.

That will not get you to 100k as at best you could go DSCR and get 80% (if numbers even work).Regarding property not complete, if you have paid cash to date, your best bet would be to get a hard money loan for $100k to complete the renovations and pay off some debt and then refinance once its completed.

Like @Chris Seveney said, private lending is a great way to go as well.  

The best way to connect and learn is to be in rooms where it's going down.In terms of captial your best bet is to focus on a primary income that cash flow sufficiently, saving as much as you can and doing something real estate related so you can get familiar with the industry.

Private (hard) money might help with renovation but will be pricey.

Where can I find private money lenders 

LouisReleasing Federal Land for private sale? 

pretty small hurdle to have a good win as a private lender just get paid as agreed.now equity participation loans those can spin the needle pretty well ..

You could put seller financing on second position and get financing for the first and do a 90% CLTV.I don't think any lender (unless private) will let you put nothing down.
