They seem like ambitious guys in their 30's and 40's who have flipped houses themselves and have worked in the finance market before starting FTF.

No real need to pay a broker fee if you are already ahead of the curve and have found/posted on BP!

I'm grandfathered in to the lower pricing of the past (was originally like $850 for their top plan, and I had 36k a month plan) - and they allowed me to add an additional market (which adds additional 36k a month) for a discounted rate.

Review all househack/multifamily listings that come on the market so you can get a sense of the inventory. 

My contract does specify that everyone on the lease is responsible for paying the entire rent.

I work heavily within the Asheville market and would love to connect with you and learn more about your investments. 

These are only given to he ones that pay their rent on time and don't cause me any trouble.

Because I'm buying at such a good price, the seller will not pay for the roof.

Their data and skip tracing isn't the best, but as you noted its cheap (you get what you pay for).

It impacts the outprice and comes down to your market data searching out areas to flip.
