Twitter and any other social media platform represents the future of advertising and client engagement and we are increasing our social media activity every day. 

You may be surprised at who wants to get in on the action.Social MediaToday, social media is not only everywhere, but it is mandatory to grow your referral base.

Or I invest in the $60k homes down the road but just having the integrity of the home and quality of tenant could be an issue, but the monthly passive would be better with less future potential on resell.  

I then go on social media and try to find one of their relatives, then you can send them a personal message. 

Other than contacting former guests, posting on Craigslist and social media (which has only given me leads that don't turn into bookings), what should I do to help get these months booked up?

So if you're really good at say marketing or social media you can fill a role, if you're good at underwriting or with numbers you can fill a role.

As @Jay says it's more a matter of integrity and having the funds in case everything goes wrong.Here is a Subject To I did in Mesa as an exampleHow I buy houses for pennies on the dollarhttps://www.biggerpockets.com/forums/311/topics/67...

But there's also Direct Mail, Websites (SEO/SEM), Social Media, Wholesalers and dozens of other methods.

Social media, mainly Facebook ads, & create them hyper-local. 

No more “checks in the mail” excuses.Also we never ran credit checks before, now it is all integrated together and easy to do.Tenants like it also.Good luck
