When investing in real estate, having multiple exit strategies is key.For a single investment property, make sure the numbers work for both scenarios: 1️) If you decide to sell the home, the deal should produce a solid return. 2️) If you need to rent it out, the rental income should cover expenses and provide a profit.Flexibility is what saves you when things don’t turn out as planned.

What these $20 - 40k “mentorship’s” sell is a SHORTCUT, but it does NOT work because the PRIMARY real estate education and knowledge MUST be there in order to be able to implement and strategy or tactic correctly, at the correct time, and under the correct conditions.

They are inexpensive, they usually come with mineral rights (big plus in Texas), they typically have short redemption periods, low rehab costs, and sell quickly at the right price; they also have large ROI. 

I just don't see you being able to do a whole lot to allow you to sell it quickly outside of lowering your price to something extremely compelling.
