To my embarrassment I work professionally in real estate development but haven't done any personal real estate investments other than my primary residences.

Also, him showing up an hour late to meet me and my investor was very embarrassing for me.

You could address the elephant in the room right away in the letter, or you could keep it generic as if you do not know their situation to avoid embarrassment.

Embarrassing but it's okay!

In 2010, my wife at the time who also had a child with me, cheated on me a week before I was going to close on a duplex home for us to live and I was kicked out of her house and was left homeless for 3 months until I moved with my father (embarrassing).

Then you can fit a reasonably-sized place to eat and normal living room furniture in the open space and save your guests embarrassment.

And I'm horribly embarrassed I misspelled opportunity in the subject line.

Regarding lowball offers, there's a saying on the podcasts that if the offer doesn't embarrass you then it was too high.

I will caution you the newly painted tub is a bit slippery, even for an adult, so you might want to think about a rubber mat or something to keep from any embarrassing moments! 

He was kind of embarrassed about the situation.
