I am closing on a duplex in booming West Philly which has a bonus unit in the basement.

(extra bonus)- if you are still young as you mention, you can have roommates in your unit to help pay as well.That would be my advice and recipe to build wealth. 

It also has no door and is, in my opinion, a bonus room at the top of the stairs. 

As noted, the SBA loans are very generous in terms of rate and LTV, however the process and closing timeline must have enough time to close.

The market was very generous and forgiving. 

I am not a tax professional but I feel it is tax evasion.As a LP investor in syndications deals large enough to pay a guy 5-10K we do cost segregation in order to get bonus depreciation and write off a huge portion of the taxes from exiting the last deal.

@Javon Dixon Start with the easy stuff, like take @Joe Gore up on his generous offer!

As a major bonus she is also my realtor, so I buy and sell through her too.

I view each new flip as an opportunity to credit-card-hack:Open a new promotional card prior to closing and put all of your expenses on that card.Once you have completed the promotion, cancel the card after 6 months to avoid the annual charge (first year is usually free).After 2 cards, I now have enough flyer miles for a free round-trip anywhere in the world, it is a nice added bonus and doesn't cost anything.

Could be a surprise bonus but very doubtful.
