There are multiple classes based on size and layout of property. 

Large SF homes can be good candidates, especially with a slit layout, where the master suite is physically separated from the other bedrooms.

I will think about the layout in the kitchen Craig Bellot landscaping is important.

The basement of the duplex already has the roughing and layout to be turned into a studio apartment.

Going the route you are suggesting could be costly if there are errors in the design, layout, egress, or any other critical matter.

Here is the layout,, Main house has 3 units and there is a stand alone cedar log cabin 920 sq ft. (4 units total - 2 separate dwellings) There is also a two level garage that is attached to the main house.

Extensively remodeling the interior: changing layout, remodeling bathrooms, refinishing existing hardwoods, new baseboards, door/window casing, paint throughout.

See if your realtor can find out what the current rents are, and check how those compare with other similar properties in the area.Once I am in the property, I am mainly interested in how well maintained the units are, whether there is room for improvement (better fixtures, adding laundry, adjusting layout) so that I can increase the rent, the age of the furnaces and water heaters, and roof condition. 

We have free shipping for any orders over $3000.00 I can also help with layouts if needed.thecabinetresource.com

@Dan Buchta depends on how you lay out the operating agreement, all and I mean ALL things need to be laid out from the beginning so that there is no chance that you ruin family or partnership relationships.
