But I'm wondering if that is the most efficient use of my time? 

Is this the most efficient method?

In that process, I had to learn the ins-and-outs of getting attractive financing (SUPER important in our high cost market), the motivation and mechanics of lending, P&Ls, how to efficiently operate those rentals, all the maintenance skills, and a bunch of other stuff I didn't anticipate mastering.Also along the way was the 2007/2008 housing crash to deal with.My point is just that if there's a fourplex on the market, and you and I are both looking at it, I have a pretty serious advantage over you in getting that property. 

You might be surprised with the productivity and efficiency of one of us remote CPA's.

There is no doubt that waking up earlier than the rest of the household is beneficial, I am simply trying to make it as efficient as possible. 

Obviously, with a long-term buy and rent strategy, you don't need to "save" that money for retirement because your passive rental income is your retirement.Because real estate is so tax efficient, I think it's a better idea to compare the $300k/year physician salary to $125k/year in passive income from real estate ($300k - $115k - $60k = $125k).$125k/year is roughly $11,000/month, and assuming $150/door, that's 70 doors.

@Daniel Suarez I would say the best and most efficient route would be to leverage someone else's network.

Up to 3 can be handled in excel, but after that it starts to become less manageable for most folks.You seem like you are probably an excel warrior, but you might find that QBO is more convenient and more efficient.

While your plan isn't bad, it also isn't the most efficient way if your ultimate goal is to invest in buy and holds.

Most larger PMs are not going to change their processes or lease agreements (unless you have a large portfolio) because they vetted them upfront with attorneys and through experience and they can't have varied processes for each client and run an efficient business.
