I definitely get the passerby's that 'complain' it's too expensive, but I always end up with 2 or 3 applications from hard working, credit worthy, tenants.  

During the last recession I saw many notes that came due and even though all payments were made on time and the borrower/property was still creditworthy, the current noteholder would not refinance nor could they get anyone else to handle the refinance.

Since it appears this is your first purchase of this type of asset I want to encourage you to dig deep into the creditworthiness of the tenant and their commitment to this property.

There are loan products that are based on the property's debt service coverage (an not the borrower's credit worthiness), but expect to pay much higher interest rates, at a lower LTV, etc that a conventional 30 year fixed rate mortgage at 75% LTV. 

Banks mitigate risk by requiring a certain level of credit-worthiness and strong employment history.

Depends on your creditworthiness, income, etc.

Also look for states and cities that have a good credit rating which ensures that they will be pouring money into revitalization which increases jobs, growth, appreciation and rents. 4- Jobs and Credit worthy.

Using a credit service such as TVS, you should be able to verify their credit worthiness.    

Environmental issues are a big deal, as you are stepping into the chain of title and can have immediate exposure - a strong indemnification from the seller/lessee backed by a credit worthy guarantor is worth pursuing.

If you are credit worthy It won't take long.
