If I fail to lease it up, I am on the hook for the mortgage that month.

Is it true that 90% of people fail in Real Estate within the first 2 years?

You should be able to look it up here https://sdat.dat.maryland.gov/RealProperty/Pages/default.asp...If for some reason that fails, you can also reach out to a local title company as well.

They lock it in and then have problems with the property and then must decide between a failed exchange or going through a sale with some big problems.

They tried passing it back in 2018 but failed and now they've renamed it and are trying it again.The numbers and landlord laws out here made sense then, and they still do today.

But a lease would prove that at the end of the tenancy you expected her to return the premises as rented and I would add a line in that says if the trailer is ever abandoned or if she fails to remove it on the last day of tenancy it shall be considered an abandoned vehicle subject to disposal by Landlord.Does your insurance company know its there?

For me, for "rescue capital", the terms have to be unbelievable and phenomenal and I would rather structure it like mezzanine debt whereas if the GP fails on the obligation you could step in, take it over and they lose their ownership in the deal.Rescue capital is very risky and like VC for seed funding, you could lose it all, so it better be well worth it.

Hosts who fail to leverage AI for tasks such as dynamic pricing, guest communication, and property management are missing out on maximizing their profits and efficiency.

Even worse, most fail to take inventory of the pitfalls wheras you have a clear understanding of how to better approach your next project. 

If she fails or refuses, start the eviction process.If rent is paid up and your legal tenant has some belongings in the rental, then I would probably be kind and give all parties until the end of the month to vacate, but I would not negotiate more than that.
