Investments don't go up in value in a linear fashion like an IRR/NPV formula might suggest.Take bitcoin for example.

I would like to start using Cozy, but some residents are old fashion.

Are there mechanisms of some sort that I should have in place in order to execute in this fashion? 

We look at this metrics (among others) as fundamentals that very much so indicate a healthy market (healthy location) where not only there will be high demand for rental units but renters will actually be able to pay rent and even pay a premium for more modern (or renovated) units, giving us the opportunity to add value to our properties that way.I hope this helps.

If you have an old electrical panel for instance, it can be very costly to upgrade to a more modern service and panel. 

@Mike Dymski  having been and worked for the 80s versions of modern day syndicators and having had a front row seat to the melt downs.. your exactly right it starts off very innocently.usually because they have so many investor in so many deals they don't want the word to get out that they have a bummer.... so lets just borrow from the reserve account of  Del Boca Vista Number 1 it will be short term loan we have the right to do it.. :)  then it just starts to go down hill.also many times these high flyers are very late to change their lifestyles.. and that adds to the cash flow stress.I mean I was totally stressed in those days I got wrapped up in a Civil rico with one of them..

If you feel you have done estimates in this fashion and found a way to make a good return anyway, seems like a win.

Anyone else out there approach decision makers in this fashion?

I think overall the kitchen is going to look very modern with the plans i have and attract great tenants.

If you and your agent think your right just don't sign the release.. the buyer for sure is not going to sign the release to you.. so its just a stalemate..the title company will hold the funds until such time as they interplead it to the court .. then you both hire attornies.. and fight it out.but in the meantime most folks would come up with a win win for this and split the money in some fashion ( assuming your correct that this buyer was out of contract and defaulted)
