Anyone that really wants the property will be inclined to act fast if there are 5 other groups looking at the property at the same time.  

As an owner, if I were inclined to respond to some form direct contact then I'd have a lot of options to choose from, including several real estate agents who are likely promising much higher prices to sellers than you could as a wholesaler.

From personal experience with South Florida, I'd be more inclined to refi some cash out of the unit, and go after an existing duplex with a distressed (motivated) seller. 

If you are charitably inclined you could look into funding a charitable gift trust.

In fact the whole line of Akurum kitchens from IKEA has been replaced so I can't even replace the doors easily with something different because the mounting systems are different.My new tenants are already moved in so at this point I'm inclined to leave the patch but what can I justifiably charge the old tenants?  

I would be inclined to get a two family and then move on to a SF with the fiance but that is me.

If they aren't inclined to do that I guess you could talk to the city about any code violations, etc. 

@Dustin Mercer,At this point, it sounds like you aren't inclined to trust that landlord any more, and that you really don't want to continue to live in that house.My suggestion is to write the landlord a polite email, mentioning the twice remediated mold problem, not blaming the landlord for the mold or the way the remediation was handled, and state that you would like to move as soon as you can find a new place to move to. 

The fact that they may be long term tenants is irrelevant to your business aside from the fact that they may be more inclined to stay even facing full market rents.

And if you have time and the inclination, you could self-manage to "enhance" your experience and pay yourself the extra.Sounds like you're on the right track.
