In the classic "sweet as pie" Southern style I replied, "Oh no! 

Sweet memories.

I've taken home office deductions in the past, though, and they're pretty sweet.

Very helpful and sweet first name!

, I made the owner an offer that was too sweet to pass up. 

Based on these publicly available data and the market-rate construction cost, I think ~650 sqft is the sweet spot where you can maximize the ratio of rental income/construction cost - you can build an ADU for under $250k and rent it out for at least $2500/month.That said, if you are building an ADU for self use and prefer as large as possible then it's a different story. 

Depending on your specialty buying flips that have foundation issues might be your sweet spot.

One is housing a puppy (pit bull) without proper approval and every time I try and force the issue they claim the dog isn’t there and was just visiting (will not accept the fact that even visits are not allowed) second tenant same building keeps having ex wife visit for the weekend with large unregistered dog (pitbull rotty mix)when I call them on it they say it won’t happen again but the women keeps coming and the dog is said to be there by tenant who is disgruntled about their dog and late payment issues.

Fast forward 25 years and i'm not a rich guy (some may say so but not by NYC standards) but i have a sweet pension before 50 yrs old (that i never had to contribute to), a 401K that was matched for 22 years, fully paid medical, 2 two family rental houses in NYC all paid for and my paid off primary residence 30miles NW of Manhattan.  

Today, I went on Zillow and saw a listing for a sweet double wide.
