@Mary BurnsA 1031 exchange with a related party, such as purchasing property from your mother's estate, is allowed under IRS rules but comes with strict conditions.

Give them one month back assuming the place is in good condition at move out. 

Lets say the seller wasn't exactly honest about the condition of the property,...

@David SwitzerThe ADA Guidelines do allow a steeper slope than 1:12 if the site conditions of an existing building can meet the criteria.

You have preyed on people who had good faith in you to care for their properties, for their personal health and safety; and instead now live with ongoing health issues, legal fees, and are forced to reside in unsafe conditions.

At the end of the day, the market is driven by condition, location and price.

State Auto's exit from the market reflects these conditions.

Relax in the air conditioning after a day at the beach.

Many cities allow short-term rentals of primary residences as long as certain conditions are met, such as obtaining a business license and meeting safety requirements.

What we find is that owners in your position can do well in a set of ideal circumstances:  the home is in great condition, they find excellent tenants who treat the property with care, and nothing crazy happens.
