That's awesome, I'm really interested in building a solid real estate portfolio. Average of 1 house per year is reasonable?
Absolutely. To be honest, it was actually more like 3 one year, two years of nothing due to life changes or upgrading a property, etc.
We have held as many as 9 at one time, sold four off last year (after rehabbing all four) and are doing a rehab with the proceeds on a A class single family as we speak.
You can accomplish way more than you think, with the proper systems and procedures.
