I have secured financing from gas stations to raw land.

I first thought of a regular second property/rental mortgage and the single family home already there (vs. raw land) would facilitate this but then I would be locked in for any subdivision of the lot or new construction until this loan is paid off correct?

That ranges from mobile home courts, raw land, new home speculation,apartments, sf homes....heck, I'll buy anything if my gut tells me I can resell for a profit....I'm heading to Florida next week to see what all the hubbub is down there....I'd hate to miss out on the opportunities that I've heard about down there without at least checking it out for myself....plus I'd like to become a snow bird some day soon......

18 = 11k lot raw... not sure cost there but say for round numbers civil and survey record plat 4k ... that 15k   we pay 30 to 50k per lot to do all W P S U Storm Pavement... so 45 to 65k all in ... then back into home prices I have no clue as to what you sell for or build for but that's easy math.. and maybe you can do the whole underground portion for 15k a lot..

Since that time I have bought two more times (all adjoining parcels of raw land).

Others are talking about direct deals in raw materials (broker who trades wood products, oil trader who also brokers shipping contracts, etc).As to your RE investing.

You can own residential, commercial, raw or improved land in your IRA.

These are raw numbers and yes you have costs going in and out and your negative cash flow.Good Investing...

there is nothing in America today harder for a business person or private individual than to get a development loan on raw dirt Bottom line the only way someone with little to no experience does this is with cash from investors.. 

Has anyone ever invested with an owner of a property , that wasn’t willing to sell their property because the offer wasn’t what they could be satisfied with but they were willing to allow you to build on their raw land for a percentage of the profits, after buying in on the investment?
