One last thing to add is that when you have very little equity in a property the FHA Mortgage Insurance Premium (MIP) is less expensive than Conventional loan's Private mortgage insurance (PMI).

For exampleSignificantly lower insurance premiums.

I was just on the phone with one of my clients that does a lot of BRRR and DSCR loans rates are right at 8% these days for him and he owns about 80 doors so experienced fella.. the BRRR cash out refi is where the rates are going to get whollopped.. those buying with 20 to 30% down or more are going to find rates in the high 5s or low 6s.. so its back to the future where you had to have actual cash into a deal to get premium financing or rate . 

Purchase price: $340,000 Cash invested: $150,000 Premium quality AIRBNB making above average returns for it's locale.

If you want to move forward put in an appraisal contingency.If this doesn't work then just find another similar property in the area and make it a STR yourself instead of paying a premium.   

While this was the case, I did buy it at more of a premium and there really wasn't any room to add value. 

I was more concerned about management having any hesitations.Also, not concerned about getting sued (and why an umbrella wouldn't serve the purpose), what I'm trying to avoid is a loss on one property affecting the other properties' insurance premiums since they are currently all on personal policies.Hope that helps clarify.

I don't want to put a loan out at 12% if there is a chance my premium to risk factor might disappear in the future. 

The plan for any fix that costs more than the premium is to wait you otu until you fix it yourself.

Most landlords charge a premium for M2M to monetize the lack of stability.
