Here's some ideas, word-of-mouth (powerful, costs nothing), social media (mostly free, spend a few dollars on a logo/branding), door-knocking (free, careful where you do this), cold-calling (little-no cost, we scrub against the DNC, respect the law), hand-written notes (cost of paper and ink, place them on doors), direct mail marketing can be very expensive, but we very strategically send letters to certain property owners, which costs us postage and printing supplies.

I want to be near social life as I am coming from out of state and want to make friends ASAP.I'm thinking a budget of $400k with $200 max for HOA doing a house hack in a 3 bedroom or more.

Hes posting on social looking for mowing etc. so thats fine hell get busy and forget about it. thanks all for your help.

I have found some through listings and on social media. 

I have 11 paid off properties (plus paid off primary) Rent is slightly over $19k/mo  ($20k by years end)This bring s14,500/mo to my pocket ($15,500 by end of year give or take)Even With zero retirement savings or pensions/social security I think this is way more than you need, especially in a state with no income tax and a low cost of living.

If they refuse to give their social security number, withhold payment until they do.

Do not do showings, look at social media, or set up meetings during this time. 

Maybe handle FB ads or social media.

Other strategies that I would recommend: 1) Start with your network - Friends and family are low hanging fruit 2) Create a brand on social media and let everyone know that you do Co-Hosting 3) Network with investors - BIGGERPOCKETS and work together to find deals and then ultimately manage their property 4) Reach out to long term rental landlords to see if they would be interested in turning their LTR into a STR 5) Reach out to cleaners who are already working with Airbnb hosts who are self-managing who would benefit from someone Co-Hosting it 

We are too young yet for Social Security and even then that income will not be enough to live.
