A high property tax rate will increase the taxes more quickly as a percentage of total expenses when the property value increases.

Now, after doing this several times my success rate is around 1 out 5.   

Raising your credit score will get you far better rates personally as well as with private lenders for your LLC. 

The maximum fixed-rate period seems to be seven years, and there is generally a balloon payment at 10 or 15 years.

Fannie/Freddie (Conventional) loans aren't just about rate and transfer taxes. 

My firm has several lenders who can seamlessly close in 15 days on 'traditional' mortgages at/below market rates and we've been doing so for a couple of years now. 

They could self manage for several years, using the rental income, until the next phase of their retirement.If they have a decent amount of financial discipline, they may want to get a HELOC now before they build to get the most favorable rate.

I started off doing long distance BRRRRs until the rates went up.

Refinancing: If the lender doesn’t approve, refinancing under the LLC might be required, but LLC loans typically come with stricter terms and higher rates.3.

It’s not necessarily more difficult than market-rate rentals, just different.If you’re seriously considering this route, feel free to reach out.
