<prompt> Human: I currently have a 1400 sq ft home in a desirable location in Nashville TN. Tons of houses in my neighborhood have been bought and tore down and replaced with 2 Tall Skinny homes which got me thinking. My backyard has enough room to accommodate a humble Tall Skinny and I think its an interesting investment idea. My house is on a corner lot so each house would be on a street without being trapped behind each other. Ive had friends with similar mother-in-law houses and had success renting them out. Would this be a sound investment? How does this effect my property value? Is this idea worth pursuing?  <response>: It might be a good idea, check if it will get planning permission, and run the numbers.Good luck.
