A lot of time you won't, therefore you also have to evaluate your marketing/sales strategy to partner yourself up with the right property owners that everyone wins in the end. 

The sale price did.

For years there was fear that creation of the tic right before a sale might be viewed as an attempt to artificially avoid taxes. 

The area seems to be appreciating by $50k each year looking at previous sale’s and comparing to Redfin/Zillow current values. 

If the rents were collected after closing and they were not addressed in the sale, then you shouldn't have a legal obligation to give them anything.

For instance, you can filter MLS or Zillow data on the number of sales per agent.

If your DSCR has a prepayment penalty, you'd need to make sure you account for that penalty in the sales price to offset it. 

Check the comps for sale prices by square foot. 1666 sqft sales for 419k for example  Residential build cost and commercial build cost are different.

I would include in your future offers that you want sellers to show proof of lead cert, if not have them pay for it as a part of the sale if it is not present. 

Generally your hours working at BP as a W-2 employee would not be part of RE professional hours unfortunately.For those who are RE professionals, gain on sale of rental real estate is still capital gains and still avoids self employment taxes just the same for those tho are not REPS so there is no downside to being a REP in the example you provided Scott.
