You must have sufficient discretionary income left over, based on a sliding scale of geographic region and family size. 

Whenever you are buying a property out of state you should do a few things to ensure it's as smooth as possible.

If your basment does not meet current code, egress windows or full walkout basemnt, not a garage they do not count as egress as well as head room then you will be required to rip it all out, or they will let it slide as finished storage space, which the kitchen will have to still be removed.

The more I can smooth the way for the tenant to be a "neighbor" with the neighbors, the better for both of us.

Very good protection for 12 months if any income slides.

It can also lead to a smooth leasing process with the tenant consistently paying on time and referring your business to others. 

Sliding doors open to private backyard with mature landscaping and deck area.

That type of realtor will work with you as your guide on the specific neighborhoods, type of properties, property tax expectations and will ensure a smooth process.

I have several spreadsheets for this, for that, and such....but it's all piecemeal and I want a smooth system in place.

Some months, everything sails smoothly, and other months, when you break the fee down, I work for pennies an hour on a particular house.
