Well, I wouldn't say I had prior experience but had the luxury of being around "old-school" investors.

HOA fees are rough for borrowing on investment properties in this interest rate environment too.

But all other sub-market is still going to All-time-High still.btw people is actually only leaving san francisco, especially the city part, for Single family with good school it's the strongest market in the country still.

Looking to get into my first STR in the next few months out in the Knoxville/Oak Ridge/Gatlinburg area(s)....I understand getting average daily rates, occupany rates, mortgage, saving for maintenance/CapEx.

From what I quickly read in the link above, seems like you just need to have a bank account that is govt insured and earning interest, doesnt have to have the tenants name on it, but you need to inform the tenant of account and rate the account is receiving. 

So if they pay more it is not that they pay over market rate.

These situations often require immediate attention that might not align with your available hours due to the time difference.Regarding property management fees, these can vary widely and you might find that the rates are more reasonable than expected.

I’m sure audit rate on this has to be astronomical and just need good records?  

So the point of this is that what often occurs is that in the year that you close on your purchase you start out at the seller's old property tax rate.  

It requires the borrower has significant experience and is very costly (in terms of rates/origination)It's generally really risky to do 100% financing especially if you are inexperienced.
