I’m currently working on a deal in Fort Lauderdale & actively looking for financing solutions like hard money or private lending.

This way, you can easily revisit details and pick up right where you left off.Avoid cutting corners to save money, as it often costs more in the end.

You should be able to send it to the court clerk with the case number (you should be able to find it online or call the court).

That will determine if you could sell it and use the money to buy a single family home or would need to take out a mortgage. 

Alternatively, I could explore hard money lenders.

Interesting idea, but I suspect that would create more problems than it is worth.Most of the leverage you have with a NNN lease is that you are working with a company, presumably one that makes money. 

The owner lived in Utah and was making too much money as an orthodontist to worry about his run down property.

A few other methods cost some money but is usually just throwing away small amounts at a time. 

Even though I wasn't a good asset manager, I made money on my properties.
