Mold on hardwood floors sounds little unusual but I guess not impossible.I would arange to have the Father meet you there so you can both look at the apartment together and both see this alleged mold on the floor, and if there is mold than sure you can early get it remediated relatively cheap.Had there been a flood,moisture or any leaks in the rental unit prior?

It's not unusual for a home builder to require money up front.

If the LLC was setup with Articles of Incorporation but it took additional time to draft and agree to the Operating Agreement, that is not all that unusual as to some extent the members entered into the LLC with some form of operating idea.

This isn't really an unusual situation.

But I never advise not having an attorney in any matter, but this request was rather unusual.

3 unit is unusual as they are generally larger in size about 6 to 10 units for small strips.Built in 2013 you are saying they are all mom and pop tenants which is also not the norm on new product.Some areas are cap compressed.

As @Dion DePaoli said, it's unusual for the second to be satisfied, if it was.

Highly unusual situation it this day and age!

I usually would add an unusual piece....a higher end upholstered piece or a lecorbeusier (spelling sorry!)

I'd also say it's unusual for any rehab seller to provide an appraisal -- almost unheard of.
