Even some small items are quite a bit more time consuming to complete than you'd think, especially when you are training yourself on them as you go.

There are many ways, much cheaper and personally less time consuming, to learn how to figure out the value of a property. 

I have found that older neighborhoods and larger houses on corner lots usually have hidden extra units in them, but these don’t show up in search results and finding them is time consuming.

Getting rent comps is one of the most crucial and time-consuming parts of underwriting.

For business to consumer and especially in real estate, we need to look like someone who's capable of handling an investment worth hundreds of thousands of dollars. 

I would advise consuming as much content on personal finance and real estate investing as you possibly can without feeling burned out.

Landlord - Tenant relations are important when living on the property being rented, NEVER make agreements outside of the lease, NEVER let relations so much as appear as anything other/more than professional, single-family is a slow road to financial independence, older properties can be very time-consuming and/or expensive to maintain, but the most valuable thing I believe I have learned so far is that the value of a quality tenant can far exceed the monetary gain of a small increase in rent.

With my current income and work ethics I could pay off consumer debts in nearly 6 months to a year, but would of course miss the opportunities potentially in the area of real estate investing.

Consumers, and Investors that work with him do not work with anyone else after.
