I had got accepted on a third, but was outbid during court confirmation. 

I have tried calling the Trustees to confirm if a property is saved or not and they were no help.

This may be the case with your neighbor, especially since it appears you've been monitoring the supposed activity the neighbor claims and seen nothing that confirms this.Some home owners are just nosy people who would rather see an empty building than tenants living there.My story....we once had an incident where a young man decided to ride his bicycle down to the local Kroger very early one morning to buy his uncle some soda. 

Sounds like he knows what he's talking about which is what I thought so thanks again for confirming.

We use a cloud software called Pipedrive that we were able to tailor to our specific needs.

Confirm what the land is zoned (approved) for.

Did you pull the credit scores for these applicants, talk to their previous landlord (not present) did you confirm their employment through viewing consecutive pay checks etc.

Your tenants sound like they are willing to endure the project but need a confirmation that the issue is getting handled by a person that's qualified with the mold issue.I had very small issue with mold behind a 4 inch piece of plastic base wall coving under a wall sink in bathroom.

This could be an oversight (automated billing software set up incorrectly, etc) or maybe they always do it but would remove the fee if you questioned them on it.

I know I can have 3 units per lot like a triplex so I'll have to confirm that I could do (3) sfhs per lot.
