You're better off focusing on specific markets, specific neighborhoods, analyzing numbers, and building an ideal buy [box].

In my market, which is a fairly economical place to build, I am friends with full time builders that are in their properties about $150k/door for construction level finishes.  

But if you/your team like to spend some time building your own flow, feel like it's better to build it on go high level directly. 

Then I begin to research the industry.

Noone bring me any REALLY good deals for the next 1-15 days, or I am subject to counter claims...Real estate industry.... get your act together.

House hacking is a great start in building your portfolio. 

My wholesale business found the deal, I bought from my wholesale business to build my portfolio. 

@Julie Doke: Industry specific software speaks to you and you can easily relate it to your day to day process.

Glad you are setting aside money, but if the HVAC is 20 years old, or the septic system has never been pumped, or the roof is 25 years old, etc; you will get hit with a cost before your build up enough set aside.How stable is the other tenant? 

But I’d say the key to success is building a reliable team on the ground.
