In southern Florida I fund and profit / loss is 50/50.

Make sure both parties fully understand and agree on:How profits/losses will be split Who is responsible for what (e.g., repairs, management, communication with the seller).Exit strategies in case things don’t go as planned.When you do find the right partner make sure to create a joint venture agreement that outlines all of this clearly.

I lost money (opportunity loss) but I gained a wealth of experience. 2.)

I am very sorry to hear about the losses that others have experienced. 

There are many people that FOMO bought in the last 18 months and are desperately trying to get out now at decent losses.

The foundation was already approved, permitted and finaled years ago for a 3400 sf house, and its solid and I won't be building directly on the overhang edge; but rather back away from the edge a few feet to prevent any load issues all the weight will be on the longer sides of the existing footing.

If I had to pay my cleaners on top of the loss income it would impact even more as my cleaning fees range from $100 to $400 depending on the property.  

There are several things to fear money loss on a bad investment, government involvement in RE, bad tenants that cost time and money, hidden maintenance issues and/or land issues and the list can go on.Today, I don't fear money loss or tenants,  the big unknown is how much the government wants to get involved in either taxes or landlord/tenant issues.

Can you take the loss without completely ruining your finances?

It will be a lot of hard work for little to no pay (or loss) until you hit a point that will be long and hard.
