But I think going back you have to have the strong mentally to endure the pain and become discipline enough to get through the hurdles that may come your way.

Keep working for and on other deals to keep from mentally committing to this property before you agree to win-win terms for you and the seller.

But I see that campers are not real estate, tiny homes are though :) I'm mentally stuck.

You need to prioritize this in respect to your time.

Actually that very mentality is what leads to newbie wholesalers trying to sell lemons as "smoking" deals.Your sales price should NEVER be based on what you bought the house for.

In fact, that's pretty much how markets work in general, and barring the occasional mistake, how we should expect them to work over the long term.As one example, the TK who is very good at the initial acquisition and rehab might be happier to simply liquidate right away, with a $10k profit, still leaving a healthy cap rate for the buyer, putting that money and mental energy immediately to work on the next deal. 

Not trying to pee in your Cheerios but many of us that have been residential REI since the 1980s actually remember the great recession, the bubble mentality, and what cycles actually look like.

This aggressive mentality will fuel your ambition to take control of your life and do what needs to be done. 

Now prioritize your properties based off conditions (the rougher the house, the higher the priority), owner name (estates highest priority), mailing address (further away the better), tax delinquency (the higher and older the delinquency the better),  and which ones have an expired listing.  

Mentally, though, I also feel like holding a lot in my savings account is a motivator to step on the gas any get myself a deal, because the money is sitting there and waiting to be put to work.
