I attribute my ability to invest “remotely” in SFHs to a team of people I’ve gathered over the years that look out for my best interests; primarily an excellent real estate agent and an outstanding property manager.

In a performing market, it's human nature to attribute our gains to savvy investing (rather than overall trend) and to  thus over-allocate due to inflated confidence.  

typically cash.. but as has happened for this investor he was able to get financing.I attribute that to :1. his dad lives there so they have a local presense2. strong PG  strong credit and income3. some history in owning rentals not their first rodeo4.

In a larger facility the tenants will pay higher rents if the resident manager is there (helps make their lives easier).4.

The property manager is not spending their money, they're spending yours.

Also this all hit brokers that were focused on running "sweat shops" where teenagers were running the office and the branch manager is the only one with the license.

I bought my first property at 28 and am now 32 (and 3 weeks)We are closing next week on properties 19 - 21 and I would attribute a large part of our success to having well paid corporate jobs and living well below our means.  

It would be a partnership probably or a great property manager I could pay monthly.
