I'm also reluctant to attribute revenue sharing based on units/acre because the overall shape of both parcels combined yields higher density if and only if the retention pond is placed on my parcel.Thank you very much!

I will say there are a lot of variable to consider other than origination points and annualized interest rates, but generally I'd say origination points are likely between 1-3% of the loan amount (paid either upfront, at payoff or a combination of both), and 10%+ interest only payments for 12 months (could be more or less) and generally want a 1st lien only.

If you are looking to combine the 4 properties into 1 portfolio loan into your business name this can be done, you can also cash out REFI. 

If you're planning to sell in the next 5 years or so, your tax benefits probably won't exceed the costs to conduct the study combined with the increased tax due at the time of sale due to recapture.   

Originally, as stated I intended to flip the house, but since I have decided to rent the property out after updating and modernizing it (FHA requires I live here for 2 years :(.)

Problem is its just combining with whatever is already on the surface layer of the wood, not removing or really covering it up.So, you probably didn't want to hear the obvious answer because it’s the most labor intensive and incredibly messy; sanding.

If a couple rent a house, I require them to make a combined income of 3x the rent.

And then there’s East Star, where you can get modern finishes and decent standard cabinets for $2-5000. 

I prefer oil (modern equivalent is called alkyd) on cabinets.

With that said, we have a combined nearly 20 years of experience in the hotel and travel industry, so that really helps when it comes to dealing with those problems you've come across (cleaning, amenity maintenance, etc), as well as the BOH operational systems required for maintaining multiple units.
