I don't have first hand experience with STRs, but from my experience hiring Remote Assistants directly I think that sounds like a decent rate if they provide the advertised services at a high level.

Man, I'll take 18% CoC anywhere I can get it, provided the deal fundamentals are solid. 

I am currently seeking recommendations for insurance agents or companies that can provide coverage for my property.

Though, keep in mind that HELOC rates can fluctuate with the market, potentially exposing you to higher interest rates down the line.On the other hand, a cash-out refinance could lock in a fixed rate, providing stability/predictability in your monthly payments.

I am good for a credit check and can provide the lease proving $1250/m income. 

In order to provide this outperform service for STR, how many units can you most have to justify your time/effort?

If you want a better output you can always add more details.Potential Improvements:You could specify the types of properties (residential, commercial, etc.) or the size and diversity of your portfolio to receive more tailored advice.You could provide information about your company's specific objectives or values for a more aligned recommendation.If you have preferences for how you'd like the scoring or rating system to be (numerical, grade-based, color-coded, etc.), that could be included.If you have had previous experiences with property managers that you found particularly beneficial or problematic, including those could provide context and help tailor the advice more specifically to your needs.If there are particular areas you are concerned about (legal issues, maintenance, tenant relations, etc.), emphasizing these could provide more detailed and relevant advice.

Before making any decisions, review the information provided by San Francisco's Office of Short-Term Rentals website, consult with local experts such as real estate agents or property management companies that specialize in STR.

This data is readily available and usually provided by larger brokers.

Not sure if this is public record or not, but i'm sure this type of list would provide great leads for wholesaling.
