Look at landlords' levels of deferred maintenance, tenant buy-outs in the millions, tenant force-outs, etc., etc.

The whole online purchasing will be changing soon for several reasons that are now converging. (1) the new democratic administration will be taxing online sales in the very near future or remove tax breaks that will force the Amazons and online stores to raise their fees/prices. 

I would start nice, but I would be a lot more forceful if they are unwilling to play ball

Its covered under the FCC and forces telemarketers to still follow the Do Not Call List even with ringless voicemail.

Also the economy of that location or state could be harmed and you would be harmed (even if you did really well in a downward spiraling market the market forces may overwhelm you advantages).Diversification is definitely a wise move to be safe. 

You can't force him to work with you - and if the house went to his ex in a divorce settlement, he doesn't have the right to enter into any agreement on the property - regardless of the name on the tax bill. 

If the property is then forced into a foreclosure auction, the first mortgage would be paid off, then any senior liens get paid, and then the lien that was assigned to you would be paid (in full) -if there is enough equity in the property, or you could win the property at auction for just what remains on the mortgage and senior liens.  

@Randy RodenhouseI don't disagree with you, but I don't think there is all that much difference between a break even BRRRR in which you've forced a bunch of equity and a net $100 a month BRRRR in which you've forced a bunch of equity.I'd do either of those deals. 

A BRRRR deal should cash flow after refi so you get both the forced equity appreciation and cash flow.

I have never been through that process, and, although my properties are all in exceptionally good shape, I am worried about the disruption to my business that might ensue if I am forced to go through this process.
