A public open house, well advertised as opposed to an agent open house, which is a waste of time in my opinion. 

FOAC has marketing pieces that are advertising financing on vacation rentals, which I'd love to obtain.  

The deal was advertised in a local newspaper How did you finance this deal?

That would be a relief for you and the tenant.I'd start advertising right up there with the other 1/1's in the area, if it's not getting interest, lower it a little until it does.

I'm wondering how this all went down without something unethical taking place...For your reference and anyone else's here, NAR Code of Ethics states:When an opinion of value is formed for a member of the public the opinion shall include the following:-identification of the subject property-date prepared-defined value or price-limiting conditions, including statements of purpose(s) and intended user(s)-any present or contemplated interest, including the possibility of representing the seller/landlord or buyers/tenants-basis for the opinion, including applicable market data-if the opinion is not an appraisal, a statement to that effect-disclosure of whether and when a physical inspection of the property's exterior was conducted-disclosure of whether and when a physical inspection of the property's interior was conducted-disclosure of whether the REALTOR® has any conflicts of interest (Amended 1/14)Also "REALTORS® shall be honest and truthful in their real estate communications and shall present a true picture in their advertising, marketing, and other representations."

Sponsors must have a pre-existing substantive relationship with investors for those deals. 506(b) deals cannot be publicly advertised.

I also set up my ads with pics and then copy them to other advertising venues.

If the deal is still there, its a high likelihood that its not a deal.Some of the worst at the hype game are the big boiler room wholesalers that advertise they have 20-30 "deals" monthly.IMO pick a neighborhood, drive it, go to every single open house. 

I recommend setting up keyword alerts for each area as they are discussed in the forums daily with advertisements posted in the BiggerPockets marketplace hourly.One thing to note when looking at the individual markets, you can make or loose money in any market.

You cannot solicit or advertise.
