What is something you could use to make your real estate career simpler, easier, more efficient, etc...

My question is what is the most efficient use of my time for building up this business?

I also had some help from a very good investor and friend, who literally saved my a*** by recommending reliable and cost efficient contractors.

I also own 50% of a construction company and my role in the company is the business side (accounting, legal, marketing) as well as growth and overall efficiency.

The lender was very efficient and financing was a breeze. 

I installed a deadbolt in the adjoining doors and have rented out each of those bedrooms as "efficiency units."

I am also trying to learn how to efficiently and effectively use the analysis tools available on BP.As time goes on, I look forward to meeting and working with other investors here on BiggerPockets. 

At which point we were able to raise rates substantially and continue to run the property more efficiently through better systems and management.

Using cap rates as a comparison of similar properties in the area can give you an idea of how efficient your property is.
