For a live in flip, all bets are off.

I bet the management is just as overpriced.

I will go back and make adjustments.  

In short, you should focus on major electrical, plumbing, foundational, structural, or environmental factors only if you want your best bet of negotiating down the price.

So, if things continue to move forward, I may have to adjust my original offer to account for the extra ~$5,000 that it turns out each property owes, or I may have to restructure the deal altogether.

If you decide to sell parts of that property then you are selling a % of the property entire and the gain should be calculated as the same % of the adjusted cost basis. 

if they leave for the summer you have a golden opportunity to adjust rents and do some upgrades. i hope you are getting good cash flow. inform them soon that the rents in august when they come back will be a certain % higher due to upgrades and its first come first served. if they are not paying rent over the summer take a nonrefundable deposit to hold their unit and dont do upgrades, just upgrade the empty ones & put a sign out "brand new ...." whatever.

Overall what they've done is a road of good intentions that will lead to hell for renters, because the net effect of that will be to increase rents as landlords hedge their bets against undesirable people.

I suppose that’s why I’d bet no one would hire me to be their sales director, LOL.

For the average person the risk of a variable rate adjusting is not worth saving $50 per month as compared to a fixed rate product.
