Blinds in a home by itself do not appear to be an unreasonable request and actually, you want to consider adding just as an extra amenity. 

I’m currently building a team to work with me on house flips and rentals, and I wouldn’t want this land I want for mostly personal use to mess with those goals.Some initial ideas on adding value to the property: -build a pond w/dock, add a food plot, maybe a small cabin to attract hunters/outdoorsmen-fence some or all of the area to make a small profit (enough to cover property taxes?)

Though, they may have the crews necessary to fix up the homes with extensive damage.

A LLC seems like the logical venue to achieve an offset to this year's taxes via MACRS along with adding to the basis with this year's improvements to the home, property taxes, etc. and luckily we already have one in good standing.  

There's been cases when someone bought  dozens of properties subject to, fell behind on all of them because of tenant problems on some of the properties, resulting in dozens of motivated sellers, thinking they solved the problem dumping the problem on a rescuer, losing their homes, and having bad credit to boot.There were extensive discussions on real estate boards regarding the issue: Subject_to_problemsIf you're taking about a 2 year master lease, maybe you're thinking of leasing with option to buy.

I added two more words and it seems happier now.

How do extension/renewals work? 

The new tenants chose to keep those appliances in place and I added an addendum in their lease that stated they were responsible for any costs associated with maintaining those appliances -- I continued to be responsible for the stove and refrigerator.  

The Comp Sale method and REI in general have enough variables in them already for the average investor; adding in the wrinkle of buying above market value is not something I'd do in general.

The route of adding a second will probably be the cheapest.2) Ask your current lender to refi the whole portfolio.
