Once you start building more than two Townhouses in a row, then you start to get the repetitive pattern that you are talking about. 

After that the rest is just a repetition.

When I bought it a couple of years ago, it was significantly less than On Screen.My estimates are very repetitive so I did not invest in their estimating software.  

For 2 units I would pay about $21 per month and have almost all repetitive tasks required in property management automated. 

@Tim Boylanthere is no secret - it's just volume and repetition.

@Mason Adelman real estate books will get repetitive but I would start with Rich Dad Poor Dad, Millionaire Next Door, Set for Life and any other bigger pockets book on a specific real estate strategy that interests you found in the bookstore.

Even if all were investment properties, it's not enough repetition to have the needed processes, experience, and resources.

It should only take you about a month or two to contact everyone on your list and then the tough part – you start all over again.Why the repetition?

As with any excel UW model, repetition, repetition, repetition has also been a big help.https://www.udemy.com/user/justinkivel/He also has an advanced course that includes various stress tests, next buyer analysis, hold-sell analysis, CF distributions, Uneven waterfall CF, EM (Equity Multiple) waterfall hurdles, clawbacks, etc... 

The more repetition you get, the better you will become at recognizing great deals in your market.
