Have you gotten preapproved yet to know what you can qualify for?

In general, a tenant is responsible for damages caused to a property, and even disabled tenants who qualify for reasonable accommodation and who alter the premises to meet their needs are responsible to put the property back into its original condition at their cost.

First, qualifying as a real estate professional for tax purposes requires more than just 100 hours of participation.

Once tenants have viewed the property I go in order of the first qualified tenant that says they want to proceed to the background check.

But you left out a keyword “qualified”.

With Nomad, you're paying a lot of extra money for a guarantee that is not necessary with skilled and experienced property management combined with masterful recommendations for property condition; i.e. what a property needs in order to be rent-ready to the degree that qualified candidates will be attracted to rent the property. 

This helps break down the purchase price between the land, the trailers (which may qualify as personal property), and any improvements like utility hookups.

Our mortgage was significantly higher than our flood insurance, and I don't know if we qualify to try to apply for FEMA or if there is other assistance, and if so, if we would apply as a business (we file it on our personal taxes as rental income).

The asset has to qualify, it is typically not based on your personal qualifications.

My question is once I have a deal signed for an apartment with seller carrying back down payment I need a partner/guarantor which would help qualify for bank loan with their income and cover closing costs.
