If anything, have a small sign in front of the house that says who the builder is and phone number (that's common for contractors to do, and also so that neighbors feel they have some to call if there is dust blowing from the site or whatever), and then you may have people calling you asking about availability (people always want something more that they had to chase and can tell their friends the story of how they got the house). 

Hey,I was asked what a typical Gator Method deal looks like recently.Each Gator deal I do is different in some way, but here’s how a recent one played out.It was with someone who’d already found a property AND they’d got a buyer for it.I didn’t have to do ANY of that work.All they needed was the earnest money for the deal which is why they reached out to me.We talked on the phone and agreed on my rate for the investment.I then sent him the paperwork and wired the money.Simple.And the result?

Just got off the phone with another DIY landlord looking to hire a PMC.They really didn't like our response to their question, "How long does it take you to find a tenant?"

For example, say I have a foreclosure, or expired listing lead that I would like to find accurate phone numbers for for prospecting.

Does AHP have an investor portal or just email/phone for fund subscriber communications?

Try calling the PM from a different phone number and also try the number on rental listings (if it is different from their main number).

Over the phone (because I was on vacation), I called him and told him he needed to return everything or I would file grand larceny charges.  

One, societal norms that your phone only rings these days for someone selling you something or something bad happening.Two, these are passive investors.  

Then they stopped answering the phone it’s been four months.

My experience with friends/some clients is get their numbers via whatever method you can and reach out via the phone.
