Assuming that you have to pay taxes, closing costs, realtor fees, etc, and you are left with 300K to invest, here's how I would invest it in the Denver market to achieve your goals:I would buy three large single family homes (6+ bedrooms, 3+ bathrooms) with basement apartments with separate entrances that cost between 400-450K with 20% downpayments in Westminster, Lakewood, Englewood, Thornton, or Northglenn, also, these houses would ideally be separated from the top and bottom (ex. 3 bedrooms 2 bathrooms upstairs, 3 bedrooms 1 bathroom downstairs), so you could rent by the room for a premium on the top rooms, and rent by the room on the bottom rooms or rent out the whole bottom unit to a family.

Do you operate the wholesaling side and the MLS listing side as two separate businesses?

Have you actually stopped and thought about it logically with the bottom line in mind or are you simply having an emotional knee jerk reaction to something that displeases you?

Is each unit a separate bid?

We are a family of 5 so adding a couple of extra bedrooms, an extra bathroom per floor, a separate living space on second floor, extra garage space, brick/stone exterior, upgraded flooring and countertops, lots of closet space, etc.

Would I have to do a separate asset transfer? 

It also applies if the spouses establish a separate entity such as a limited liability company (LLC).In community state, husband/wife LLC can own Primary residence and elect to be classified as DE, and qualify for section 121

Also, they don't want the landlords to get emotional about small things (i.e. clutter).Solution:  While you can't go inside with them, that doesn't mean you can't meet them outside. 

For these reasons I calculate general capex, opex, and turnovers as 3 separate buckets in my spreadsheets.I agree that the NAA surveys are a goldmine for this.

They are separated by a fence so they each have a private yard and separate in house laundry.
