I live 20 minutes from a military base.

Is it ok to use this lease or is there a special lease out there for leasing residential properties to a business?

Establishing relationships with local real estate agents who specialize in investment properties can be incredibly beneficial.

Research or get referrals for RE brokers or wholesalers you specialize in off market deals and develop a relationship with them. 

I specialize in this area.

We're a direct lender specializing in bridge, fix and flip, ground up construction and DSCR .

But it becomes a much less attractive investment to an outsider when you know you could be facing future special assessments like that.  

I specialize in single and multi family investment properties.

What @Jay Hinrichs is saying is that if you go before a judge, and you show that these leases were signed for significantly under market value and signed just a few days before closing, there is a good chance the judge will side with you because it is an obvious attempt to pay less rent and take advantage of the new owner.I think your next move should be to contact an attorney in your area who specializes in landlord tenant laws in NJ, and see what they recommend. 

Nick1st of all I would recommend not eating crayons, I don’t really understand military humor but if you are eating crayons I’d recommend taking care of that issue before you are ready to buy real estate, 2ndly I’d make this decision based on where you want over where to “invest”.
