Ask them to share their STR management VRBO, AIRBNB etc, and look at their costs.Use their vendors if they offer positive opportunities and use that as a way to ask for "Earn your Business' type discounts.

@Joe Villeneuve I recently put an offer for a condo (< 100k) and got accepted - it was all cash offer.

Hardly anyone offers it and if they do either generic national companies or small ones that aren't marketed very well...

I’ve had the property listed for three months with some interest but no offers.

Go to meetups, offer to help people FOR FREE, ask for book recommendations, read the books and follow up with the people who recommended them. 

lot size .31 acres or 13,503 SqftSchool district Hendry County Zoning RG3I just want to help my neighbor, he has been getting offers from $1 to 30K....  

Offer only the land value . 

I am trying to place an offer on a HUD property.  

My best advice is to find someone who is doing what you want to do, and then offer to bring value to them (for "free") in return for mentorship, guidance, and knowledge. 

While specific neighborhood recommendations can vary based on current market conditions, areas close to universities, medical centers, and business districts tend to have strong rental demand.
