So, you can do a land contract for 12 months, which should allow lender to credit you full value of the land vs the purchase price, but the loan will pay off the land contract, so the lender maintains first lien position.Can't help you with the rest of your question, but you should be able to search for "CPA" here on BP to find experts to reach out to.

Step 1: Get preapproved for an FHA loan for the purchase price you are looking for.Step 2: Connect with builders until you find a few that will finance the construction of your home. 

I’m looking to raise $160,000 to cover the purchase, renovation, and activation of this new Airbnb property.

You can increase returns with leverage (that is a mortgage) or with value add (renovations, additions etc).I think cap rates (rents minus expenses divided by purchase price) on commercial and industrial is higher with less work involved, but its more expensive than I can afford--so I know next to nothing about that land.

Land is valuable as I could purchase a new mobile home and install and less costs since utilities are already on the land. 

I have helped many new investors purchase their first property in Memphis and LIT.

The purchase contract makes the buyer legally responsible for the loan. 

You can potentially purchase multiple properties, which is a huge plus for spreading out risk.

Quote from @Jaren Taylor: Quote from @Stuart Udis: Depending on the transaction sizes you are pursuing, raising money to purchase property without debt requires either an incredible network of relationships or devoting a lot of time and effort to raising money.

You can find some 2 units under or around $250K but they have been sitting on the market for over 150 days which tells you its not a great deal if it were an investor woud have already purchased it 4 month ago.
