For me it is also a reminder: the numbers have to work.

I'm in the Tampa Florida area and it has been very accurate for me and my units. 

They said this is an older home, and has had some minor renovations but it probably would need some form of work if comparing it to the fully reno homes in that area.

For me my main goal and I achieve was being able to put them through collage on  my dime and then set them loose with no burden financially.

The short answer is: file form 1099-NEC. 

Then I'd probably spread that $750k out amongst numerous operators and diversify across asset classes that I like (for me it would be industrial, multifamily, storage, and mobile home parks).

I'd estimate that there are less than 1,000 legitimate, or "professional" wholesalers, in the United States of America, as defined by individuals who make $100K flipping contracts, and collecting assignment fees, in any form, and who have made that amount of income more than 3 years in a row.

Then you can determine whether or not to hang on to that one or seek something somewhere else.Even the decision to move into other asset classes like equities or whatever will need you to factor in the loss of investing capital in the form of capital gains tax (plus 5 years of depreciation recapture). 

For me the area I was concerned with was estimating costs.
