Desired houses sells too fast, should I make off market offers?

[Ryan DeRobertis]

It seems like properties that I like hit the MLS and go under active contract within the day/hour sometimes even over weekends. As a semi-remote buyer(buying/visiting in Philly, working remotely at myrtle beach), it is hard to compete on timing let alone a bidding war. Having listened to a lot of guests suggest somehow contacting owners and seeing if they are interested in selling despite no for sale signs, it got me thinking perhaps I can do the same?

So would it be illegal/wrong to print some flyers or cards about wanting to buy specific houses and placing them on the houses I like as I tour neighborhoods? I am in Philly for 2 weeks and then going back to the beach until I return for more touring/streetwalking.

Anyone take this approach before and have suggestions/advice?

Thanks
