I think we may see a return of bonus depreciation, but I doubt that it'd come without a cap of $1-2m, and a repeal of Sec. 179.

BIG bonus is you snag something with Timber that will grow and you can do a selective harvest 20 years from now the Timber could end up paying for the building of the home.

Any stats you can provide would be a bonus. 

@Mike Levene First note, I agree with others saying cash flow is a bonus, though it depends on what stage of investing you're in.

The ADUs that the most experienced are adding leverage bonus density program or other such rules to add multiple units and for the most part they exit.  

Plus, as mentioned your risk exposure would be huge if you didn't have a contract in hand to lease, plus they won't want to lease from you, because they are a Sticky or capture tenant.Start small and Make Your Big Mistakes Early.

Although Philadelphia is only requiring you to get General Liabilty, I think you have a bigger exposure to Professional Liability (E&O) insurance. 

If you need assistance in flipping a property, or really any job an inexperienced person can do, I am very interested for any exposure I can get to real-estate investing.

You need to understand that given your situation the asset and operational impact must be absolute minimal, lowest risk exposure possible.

Bonus Tip:  Find a distressed HUD Home (google Hud Home Store) and you can buy a house for just $100 down!
