There is not a lot to it as long as you paper your tenant when appropriate, always deal with issues as though they will be reviewed at some future date by a Judge.

The age would not matter as long as the property was in good condition and has been well kept.

However, I am not attached to any region in particular, as long as it is a good deal in an easy to rent area I would be interested.

My criteria here is 600 score and up as long as it is paired with no criminal, evictions, and good employment reference (landlord referral too if I can be sure its truly a previous 1 or 2 landlord).Back to Sec8.

That being said I would do it again in a heartbeat so long as there is enough profit in the deal to share with the next guy.

There are no taxes on any of the income or even real estate sales as long as the funds stay with the 401(k).

As long as there isn't, you can give notice to quit as they are MTM tenants. 

As long as its in escrow your safe.

As long as you've both owned and occupied it for over 2 of the last 5 years you can sell it and exclude up to $500k from taxes. 

I am not sure the broker can prevent you from acting as an agent as long as your license is up-to-date.
