I gave them time to figure out their ACH verification problems and even gave them a choice to make a payment in another way or through another platform.

Talking to a commercial lender is the best bet.

I have two questions: 1) I asked on this platform before about disputing a condo building lease fee which was $500 per lease.

Though I know it's possible for rent and prices to go down, I'm willing to bet this city is here to stay. 

The condo’s potential for consistent income on platforms like Airbnb, coupled with the area's growing popularity, made it a strategic addition to my investment portfolio.

Good luck. haha i would run away from anyone self-proclaiming as "financial expert" with the expectation to "meet the guru / mentor/coach / master of all business" in his/her personal residence lol I have not google him yet but I bet he is taking picture in front of luxury house and driving sports car ?

The leads are marginally better than other lead platforms like Zillow. 

If so what platform do you market it on?

Quote from @Audrey Sommer: The best method is to syndicate to many platforms.

I am accustomed to the platform and implemented it in my newly started STR property management company at the Jersey Shore.
