As you know, an RM, once triggered by the incurable breach, requires a balloon payment of all unpaid principal, interests, advances, costs, etc. 

1) send them some yellow letters or if your ok with cold calling like I am then look them up on spokeo and get their number.

The law says that no unlicensed entity can receive 'any' considerations due to the purchase/sale of real estate.That means gift cards, credit points, discounts, cash, etc at closing.Like @Dev Horn says if you pay a flat fee for each lead then that isn't a consideration for closing any transactions and it would be strictly lead generation.If somebody brought me a deal and I closed on it before paying them If I was fearful of paying them for it bc they were unlicensed then I think I would simply give them the option to have money out into a marketing campaign for them to manage.Like buying 1000 direct mail letters with their information on it bc that would be you putting money into marketing vs giving a consideration.

So far I've sent all my out of state owners letters (300) and received about 10 calls.

I do my multiple option offer strategy in the form of a letter of intent.  

I ask this because I recently started my first letter campaign (FINALLY!!)

Thanks Jon , I figured when I make offers if the seller got a letter from a company , they would take it more serious

Some of you might hate yellow letters or post cards, though they work, they stand out from the crowd.

Did not disclose it on the initial application because it was not completed yet, and as we all know things can happen right up until the last minute before closing new loans, so I wasn' t going to say I had those loans when I really didn't.Fast forward to today, Refi/HELOC closed, underwriters on investment property noticed HELOC lien in MERS so they asked for a letter of clarification regarding the lien and why did not initially disclose, I wrote a letter explaining what I just said and so far no issues (*knocks on wood*)My situation had more time between them than yours do, giving the underwriters enough time to make sure it checks out without delaying the process.

Start doing postcards and yellow letters as soon as possible.Summary - I am speaking from experience.
