I bought it strictly as an investment property.  10% down, conventional, no PMI.  

10% is probably a little steep, and like John said, a flat fee may be more reasonable.Setting up a proper STR is not cheap, but once you are set up properly, you deal with routine breakage.I recommend managing yourself and saving the 20% personally, getting a rockstar cleaning team and a reliable handy person, using something like Hospitable that can help automate messaging when listing, and reading the book from the bookstore here called Short-Term Rental, Long-Term Wealth.

As far as investing for income and equity I am moving strictly to Syndications.  

That's having certain folks handle certain tasks, and placing yourself less in the process and more in the decision making strictly area.

Taking advice from someone with a financial BIAS is dangerous to your financial health, unless you know that individual to be “above” short term personal gain and strictly in for long term relationships and reputation.  

I have friends that routinely use ear plugs in a detached single family to eliminate noise from kids, spouses, cars going by on street, etc., when sleeping.

We have strict criteria and only buy if we can properly segment risk.

Part of the value add strategy is to covert a number of the units to mid term rentals (30 days or more) as San Antonio has become more strict on STRs.

You don’t have to be as strict as a traditional lender, but it’s wise to check their credit score, employment history, and income stability.Flexible Terms for Stronger Buyers: If a buyer has a strong credit history and steady income, you could offer better terms (lower interest, smaller down payment, longer balloon).Tighter Terms for Riskier Buyers: For buyers with weaker credit, you might require a higher down payment, a higher interest rate, and/or a shorter balloon period.6.

I prefer to keep all my dealings strictly business, no personal decisions when ever avoidable.
