When analyzing your offer, make sure to factor in operating expenses, rehab costs, and vacancy rates.

I have a hard time seeing a property worth $625,000 that you're into for $450-500,000 cash flowing very well at $3500-4000/rent with where rates are these days.

Shop around if you can to determine what is a good rate to pay.

The manual entry of numbers has moved to an automated model with accurate ARV, Cap Rates, etc.  

My current company is AllState, and they increased their rates by 100%, so I'm looking elsewhere.

You might not get as much cash flow with that equity as you would get if you sold and put it into say an apartment building, but with the low mortgage rate you are likely getting some pretty good principle paydown each month and it's in an area that will see good appreciation/rent growth long term. 

The whole scheme was buy a foreclosure, "sell" it back to someone that can't qualify for traditional financing with seller financing at a higher rate, once note is "performing" you can sell the note and make a lot of money.
