I'd recommend recording the lease signing so that they're on camera/audio agreeing with the rules upfront

They'll want a copy of the plat for your lot as well as the footprint dimensions of the house to be moved (the former, presumably you already have a copy of, the latter may need to be physically measured or extracted from the plat of record for it).The physical move of the existing structure is just one scope of work among many.  

It seems daunting all the pieces I need to organized to buy a property, financial analysis, legal, accounting, real estate agents etc..

All security instruments should be of record.  

A big financial hit personally (to the tune of $15K/mo), or a hit to my excellent track record (which facilitates my livelihood) and a loss to my investors.  

Plus you would have more credibility/track record with a syndicated $4million dollar than simply owning something outright. 

If you plan to proceed with the new construction, then partner up with someone that have already gone through this process a few times (and check his/her record).  

Still, current projected rent is $3,200/month.Current owner (in keeping with the deferred maintenance theme) has very few financial records but does prove up the following actual numbers:-Property taxes, $1,900/year-Insurance, $2,320/year-Owner-paid utilities, $3,429/yearEstimated:-10% vacancy-10% management-15% for maintenance/repairs, and -Reserving $700/month for CAPEXBOTTOM LINE is $34,560 net rental income less $24,700 expenses = $9,900 NOI.Offered $95,000 with $10,000 reimbursed at closing for immediate CAPEX (roof and A/C units).  20% down, loan on balance ($76k) at 6% for 30 years.Cap rate with $400/month rents is 10.1%, cash ROI is 20.3%, and annual cash flow is $4,400. 

Farming operations have scaled correspondingly and what was the family farm of my grandparents is no longer sustainable ... in the areas where my parents grew-up, many "family" farms today are working  6 - 10 sections annually - a task that requires millions of dollars in capital equipment.There are also farmers who are specializing in organic and/or non GMO crops (both of which may require maintaining a wide border strip between their fields and their neighbours crops).There were (and likely still are) two principal ways of renting farm land in that area: a) straight rent per acre/quarter/section or b) a share cropping arrangement with the farmer working the land.  

They are way easier to work with in my opinion and as you grow, they will be more willing to be creative with your future deals if you keep a good track record.
