I know there are a few options that replace collecting a traditional security deposit.

Also people on Social Security or Social Security disability or retirement or other types of guaranteed income. yeah we can't discriminate, but a factor in your ear rental guidelines should be are they working in something that almost guarantees future unemployment

Though this is easily fixed out of security bond.Include in your ad that nuisance pets (barking, aggression) is not acceptable, include this also in your agreement.

Get it on letterhead that includes the following items at a minimum:  proof of spay/neuter, sex, breed, shots, vaccinations, county of registration, age, height, weight and colorProof of annual pet license.

The main issue you haven't mentioned is that you have too many layers of roofing up there and weight is a real concern.

I'd run it by a professional lawyer just to be sure.As you get a few deals under your belt you'll probably realise certain clauses you want added for extra convenience / security.

He knows I have a huge security gland. 

If so a lot of them might have to be put on the market as long term rentals.If the deal is marginal I would have to say move on without it, no one would blame you, the landscape has changed drastically, and is your income secure?

I personally have no idea what might happen, so I am taking the strategy of securing month to month tenants in 50% of our properties. 

Financially, I feel my W2 employment is fairly secure.
