As I transition the property to a duplex + 2 ADUs, I am considering spending $10K+ to get another master meter put in.

For some extra context, their lease expires in about 5 months, so this landlord transition happened midway through their leases. 

That is, how well did your deal analyzer estimates match the actual rehab costs, holding costs, ARV, and profit?

He asked me to fix it up and sell it, and then he'd let me keep the profit.

Relationships always build better more profitable relationships.  

@David Kendall Jr, for deals that I am managing myself, I want a minimum $50k profit potential, and shoot for about a 15-20% profit margin, whichever is greater.At the end of the day, percentages alone don't work for me, because my time has a value to it. 

Your HML may have a company they work with frequently that will make it a smooth transition so ask.

Either pay it back in ten years or when I sell I have to give a % of the equity to the lending company. breakdown$2,200-$1,100=$1,000 profit what are your thoughts?  

My syndication deals got bigger, more impressive, and—most importantly—more profitable!

As more people placed more properties in STR inventory, and as more municipalities taxed and regulated the industry, the profitability of the overall industry has reverted to a much more aligned (lower) risk adjusted return.
