Best practice is to ask them if they consider hard money cash. 

For example, for a business owner; they have no practical way to 1031 exchange.

I've been analyzing a couple deals in the OH market recently to get some practice (my research tells me it's one of the few decent cash flowing markets).

The one with evidence wins.As always, @Nathan Gesner coming through with the most solid and practical advice.If you have issues with your PM, be very direct and state your case.

Your tenants obligation was to pay you on Jan 1, so it doesn't matter if they paid someone else they still owe you...obviously details re: notice and dates all come into play here and from a practical perspective I'd work with the tenant and not move to evict over this.

If the tenant has low net worth, a court judgment is practically worthless.Taking a week to vet a tenant can save months of headache.

Find Brandon's videos on YouTube for the "four square" method of analyzing homes and practice.

Any other sympathy is unfortunately just Poor Business Practice.
