1. Looking for houses and looking for apartments are two completely different animals and require different approaches. In these cases, you can find a half-duplex house (also called a halfplex) for sale; however, what you are really looking at are two single family homes In this case, it would be more accurately called a semi-detached home (two homes that share a common wall).
If you are planning of renting one of the houses and you don’t want to be meeting the tenant every now and then, you should ask your architect to design the house in such a way that the top and bottom houses have different amenities such as parking spaces, main doors and laundry areas.
But under no circumstances ever disclose to a tenant or onsite manager that the rental property is for sale and you are considering buying it. Owners are always reluctant for tenants to know the property is being sold for fear that tenants will move out.
Also, bear in mind that though the principals are the same for any CMA, whether for houses or rental properties, our particular interest surrounds real estate investing so this article will refer to examples and instances related to income-producing and commercial real estate property.
If you are attaching the duplex to your house and using it as a rental or investment property, you don’t want your renters having access to your home, which means you need to ensure the duplex has an exterior door of its own and no access to your home.
