Selling smaller income and multifamily properties is not an overly sophisticated process but overlooking small details can cost you big bucks.  Buyers are going to consider location, gross income, condition of the property and potential to add value when making an offer.  

Pets can be a nuisance, damage property and disturb other tenants.  But, if you refuse to allow pets in your income property you could be limiting your local tenant pool.  With the proper guidelines in place, pets and their owner's can be easy to manage.
