There are a lot of influencers, courses, and coaches out there who only want to make money by selling subpar information that doesn't help people. 

Should I file suit to make them sell the property?

I ended up selling my property to wash my hands of it.

Quote from @Devin James: Gross Margin is an important calculation for developers/builders.Gross Margin = Gross Profit / RevenueWe shoot for a 20% gross margin on our New Construction HomesReal #’s:Home Sales Price: $374KClosing Cost: $18,700Cost of Construction: $258KLand Cost: $30KGross Profit = $67K$67K/$374K = 17.9% Gross MarginCame slightly short of our goal of 20%Homes Values and Build Costs are constantly fluctuatingI wish we had a crystal ball build larger homes. average new build in our market is 2200 square feet, 4 beds, 3 baths, 2 car garage and sells for 515k. construction costs lower if design is good and find the median or average home sale price and push that up. my guess is you built too small. 347k is cheap. we target 429-479k price range in columbus ohio for single family homes and also only purchase close to urban core where premiums are 20% higher and we build smaller like 1500 sq ft where price per square foot goes up. 

If you want to grow a portfolio, the math is clear, you must sell to Pyramid UP. $250mnth is not good performance.

The only situation that I think it would make sense for you to start investing right now would be if you are not investing the full $200,000 and are looking to take some money off the board and put it into a safer investment.

Thirdly, financing and potentially selling later on could be challenging again with the part of the plan being on a campground. 

Maybe they have other properties they are interested in selling without a Realtor involve.

Newton's law of tax: What goes down must come up.Everyone enjoys the sweet benefits of bonus depreciation, but what happens when you sell?

Quote from @Sarah Ali: The seller has a contract with the agent, which means they can't legally sell the property without compensating the agent.
