I'll also preface that this rental is in a market that is neither hot nor cold.

You're writing the check, so you are in charge, but you should still bring cold (or warm) drinks for workers randomly. 

Then you can mail or cold call or both.Other cheap or free methods are driving for dollars, craigslist, Realtors, FSBO sites, expired listings, foreclosure sites and bandit signs if allowed.If you have the funds you can use billboards, newspaper ads, other offline publications., TV commercials, radio ads, motivated seller website, SEO, pay per click/adwords, facebook, Linkedin, Youtube, and other forms of online advertising and boosted/promoted social media postings.Bottom line is consistency.

I might be related to the weather too, it becomes cold now. 

Try different avenues to get deals as was mention direct mail, signs, cold calling, door knocking, referrals, drive for dollars,  Get different lists and attack them such as code violations, absentee owners, evictions, probate, fsbo, pre-foreclosure and so forth.

You can also pull and very refined list, look them up on the secretary of state and cold call whoever is behind that LLC.

I am suspicious that they may have gotten cold feet.I have no intention of letting them dictate core lease terms like this.

He wants me do cold calling to set up leads.

@Andrew Rasmussen,We do a little of everything but we like to do bandit signs, cold call, and investor carrot for leads.

Cold calls, research, marketing and networking over and over again.
