So I would say pick no more than 2 or 3 markets maximum and really drill deep into those markets, really get to know them.

Refinance lender was ok and I'm actually using them again for a house hack but I don't think they'll be a top of my list for another BRRR refinance due to their restrictions.

As @Michael Baum suggested, the amount of work doesn't change with the seasons, nor does the length of stay, as @Theresa Harris mentioned.My question is... in order to compete with lower total trip costs from other listings (often resulting from lower cleaning fees), should I eat a part of the cleaning fee in order to have a lower total trip cost?

There will be pros & cons with low-down payment programs (FHA, 5% down conventional, NACA) so you just want to pick the best fit for you.

@Sage WeissInfinite Banking is a strategy and methodology that leverages the amazing benefits (see below list) of dividend paying whole life insurance.

Using a conventional loan, you shouldn't use hard money until you gain some experience and know you'll be able to refinance swiftly.If you have some experience and want to do a BRRRR, you should interview multiple GCs, see their results, and pick the one that fits best. 

If a good lawyer has a client that hurts themselves on your property and sees you have significant assets, I feel you're easy picking without some protection.  

Any way you could buy a outdated home and add value while keeping list price down? 

To be honest if there's not enough complaints to warrant a refund and your listing is a few years old with plenty of 5-star reviews, I wouldn't worry about it at all.

How can I go about obtaining a list of properties that are tax delinquent and/or have code violations?
