Im buying it tho not building it , i literally just made a post asking if the deal was "Good enough" a minute ago because of cashflow.

Given this was a duplex in a developing area, my strategy was to buy and hold with cash flow.

If you normally buy and hold and flip one or two per year cause that exit strategy makes more sense you'll probably be ok but if you're primarily flipping and doing multiple that will be deemed as running a business.   

What are the down sides/gotchas for doing this strategy?

A Tax expert who can implement this strategy for me2.

The only house I bought to live in will be fully owned by the end of 2024. Some facts of the house:Location: Nassau County, NY, Town of HempsteadYear built:1929Purchase price: 290,000 in 2013Condition: AverageLot size...

Where have you been finding success in the Huntsville/surrounding areas and what strategy?

What strategy are you thinking of doing?

My strategy is to take income minus monthly operating expenses minus financing interest expense and the rest is my cap/repair yearly maximum.

Haven't heard of this particular operation, but from my experience, you will most likely  be overpaying for cash flow that wont be anything near whats promised, and with no clear exit strategy available at the end.
