How you do it and your level of comfort with the options, is entirely up to the LLC owner. 

I’d love to hear if your biggest home runs have been from: a) buying an existing STR, tweaking it with your own unique skill set and applying your experience-proven enhancements to be a top performing property, orb) converting a previously non-rental property into an STR?

They do not have the skills so these one offs that go way off track is their business, they know you'll never work with them again. 

I have a property that I have rehabbed that is in a D level area that I would want to off load after a time anyways and was wanting to know how everyone goes about doing this.Do you have a contract that says something like "you rent from me for 3 years and then pay 100k over remaining balance of my mortgage"?

I will lever it lightly with assumable debt, or not at all, and keep this conservatism going until cap rates are ~100bps above interest rates on property of reasonable quality and nearby where I live and operate my business.If that happens next year, I’ll cash out refi to a moderate debt level and buy!

If you got carpentry skills, it doesn't look like it would cost that much to repair.

I have also purchased training from Attorneys and CPA focused on real estate.I also learned that Renatus is more like multi level marketing where you are then asked to sell this education to other people to recover your cost.

You have no real control over macro economic issues over the long term, which will have a higher level of impact on your building value.  

They put levels on the pad and check to see if there are any noticeable water entry points.

You make such a good point about concentrating on paint, trim, doors, etc …I do this all the time with my rentals - I build to a level I’d want if I was living there, not necessarily what the rent could justify in finishes.I’ve got some issues that are far more important to tackle before the luxury fliers I might take.
