I am interested consultation regarding the feasibility & design of developing rental cabin placement and/or RV campground/park.any recommendations as to whom I could reach out to regarding this?

For those STR operators and investors that are not comfortable self managing (communication with tenants, scheduling cleaners and organizing supplies) one option is to hire a designated full/part time employee. 

We plan to have designated broker-officers to facilitate transactions and referrals on behalf of our entity.

The amount of monthly income will depend on your goals and the rest of the deal design.

the REI will be able to place risk controls by knowing how to analyze markets (not properties), understand how money works so they can develop and use multiple strategies instead of relying on just one, and understanding what a plan is, and how to design one for them,...and stick to it. 

For extra formality, put it on a nice document with your letterhead.Re: Non-Binding Letter of Intent to Purchase Real Property Located at [Property Address]Dear [Recipient's Name]:This non-binding Letter of Intent ("LOI") is submitted by [Your Name] (the "Buyer") to [Recipient's Name] (the "Seller") with the intention of setting forth certain preliminary terms and conditions for the proposed acquisition of the real property located at [Property Address], inclusive of all improvements, appurtenances, and fixtures thereon (the "Property").Purchase PriceThe Buyer hereby proposes to purchase the Property for a total consideration of $[Amount] (the "Purchase Price"), which shall be subject to adjustment based on the results of the due diligence investigations and final negotiations.Earnest Money DepositContingent upon the execution of a definitive Purchase and Sale Agreement (the "PSA"), the Buyer shall deposit earnest money in the amount of $[Amount] (the "Earnest Money") into an escrow account designated by the mutual agreement of the parties.

Boom.I take this tact on many high priced or specialty or design items, like countertops, light fixtures, appliances, large glass or window replacements, mechanical anything, etc….Contractors have their preferred suppliers who they know and are reliable, but are not always the best deal.

For the IRA LLC it's a special purpose LLC that's created to be designed by the IRA. 

The words or design isn’t perfect?

Find architects or designers, engineers of all types, general contractor, etc. to design the project, and know how to keep the design where it's functional, cost effective, but has appeal.
