This isn't a green light to piss off people and run a scorched earth mentality but the notion that you must perfect everything before starting keeps many from ever succeeding. 

However, I think it's important for you to be able to prioritize repairs. 

Not worth the mental thought in my humble opinion, I'd rather put my thought towards the next deal or opportunity and not ruminate on small dollars. 

Wait until you have cash flowing properties to pay for the fancy car and house rather than using your hard earned money.6) Prioritize learning over $/hour at the beginning.

There is an issue with a tenant who is in conflict with the other roommates (she has a dog that she isn't cleaning up after, she's disruptive/ argumentative, and in victim mentality) and I think I possibly need her out. 

Perhaps they will leave peaceably when you post the notice, but even if they don't, you're very fortunately in Texas where they don't go out of their way to make evictions more painful for homeowners.I would also file the lawsuit against the former owner, who is either mentally ill (did they "forget" they sold the place?)

Then you need to mentally separate that relationship from the secondary tenant/landlord relationship. 

This is approaching it with a "buy and hold" mentality as opposed to a "fix and flip" one; that might change the calculation. 

Sustainable, energy-efficient homes are not optional - Gen Z buyers prioritize eco-friendly and energy-efficient homes.

Working with solution-oriented contractors who approach setbacks with an open mind helps the project move along as well as my mental peace tremendously.
