Great breakdown @Julio Gonzalez , really helpful to understand Cost Segregation.I want to add one reminder for all of us, Land is never depreciated, so the basis value ($641,100) of the property above NOT includes land value.

One thing that will remain true for all is the outlier buyer who would want it either vacant (perhaps for their own business), or easily turned vacant.

Most mortgage companies require a mortgage to "season" for one year before they'll sign a partial release of mortgage.

Purchase price: $75,000 Cash invested: $75,000 This is a duplex with 2 bedroom/1 bathroom on one side, and a 1 bedroom/1 bath on the other.

The all in one is an excellent option

All depends what you are looking to spend, what kind of tenant you are looking for, and what your values are for cashflow/appreciation.Once you ask yourself these questions, then you can start to pinpoint areas that best suit your needs.Also, RE is one of the investments that can become less risky the more you spend - ie a good location 

In a 1031 exchange, the same taxpayer who sells the property must be the one who buys the replacement property.

My first house-hack from 2014 looked very similar to this one in Denver, CO.

How common is it to find an investor that is looking to sell multiple properties in one big seller financing deal?

It would have been one thing if you hadn't led us on.
