I plan on completely self-managing it for a while, to really get the feel of how everything works, but the goal is to make it a scalable business.

Scalability: If you plan to expand your real estate portfolio, having a property manager becomes essential to your team.

Scalability is difficult even with a third-party management business.

I create my own products and wholesale product on amazon, this is a much safer and scalable way to make some great income. 

The accessibility, flexibility and fast scalability of this model is par to none I've encountered before.

I think it also makes more sense to do value-add here if your operation is scalable, i.e., if you are doing so many flips that you have a full time reno staff and if some properties have tighter margins than others, the economies of scale are in your favor.  2) We get sent quite a bit of direct mail from investors wanting to buy the Greeley property so I would say you will probably get results with DM as long as you can put in a bigger effort than the other investors sending out DM.  

As you start closing deals, you will need to reinvest your profits into mailing lists and other scalable activities to grow your business.

The concern over wasting time is also fixed by reducing the "cost" of your showings - mine are all automated and self service which makes them infinitely safer and more scalable. 

In summary - I plan to house-hack, Flip and Flip to paydown debt and fund scalable buy and hold from there with own funds. 

The cashflow looks great and they're cheap enough to allow quick entry and scalability.
