Your experience is not unusual, though extremely frustrating.

Usually you notify the judge of the default and go for granting of the dispossession.It depends on how the mediator wrote up the agreement.If you alter the agreement or accept partial payment instead of the payment amount listed they could make you start over.You can write a letter to the judge in unusually circumstances.Another one for you is after you get the writ the Marshall will call eventually.Whatever time you give them make sure you stick to it.They will not do a reschedule and you will need to start over again.If ti is raining on the day of the scheduled eviction then the marshal will reschedule a time to get the tenant out (few days maybe).Eviction court is only held certain days of the week in Fulton county.If you are unsure of something call in to dispossesory and they love to help but cannot give legal advice.

I'd be leary of the 90% LTV as it would be unusual at any bank, sounds like an SBA Loan guarantee and they will take a lien on everything you have!

Unit 1 is unusual since, depending on the financing direction, I hope to have less than or equal to 10k capital invested.

Nothing unusual here. 

I had an extremely unusual conversation with @Chris Clothier today.

In a scenario like this, it's not unusual for a tenant to just "ghost" and disappear with no further contact.

When someone works for a place not known to pay enough for folks to become homeowners, it's not unusual to encounter problems.

A reason I mentioned above was that this would be an unusually large facility.

The approval process may take over a month and, unfortunately, it is not unusual for loans to be denied or major issues discovered (title problems, etc.) several weeks into the process.
