More energy efficient since the window is mainly closed, and quieter since the mechanicals are outside and separated.Hope this helps. 

I don't know if this is your bailiwick or if it's more legal, but I'm interested in the mechanics of how money moves when my C corporation starts a wholly owned subsidiary LLC that is a pass through entity for the purpose of buying and completing a flip and then dissolves it after the deal is done. 

The house was structurally sound, but the mechanicals were very dated and the property needed a minor facelift ($7K).

We drive old cars and I repair them myself (by choice) since I have been a motorcycle mechanic for over 20 years.

Mechanics lien? 

Don’t spend time talking to them about the mechanics of what they do - that’s available anywhere.

Do you know bike mechanics?

The mechanics of the deal are not too complicated, although as others have noted you can't advertise the property and then exclude people based on protected class including gender and family status....at least not legally. 

Is it the end of the world if you don’t pull them if it is truly cosmetic, non-mechanical/non-structural?
