Don't think this is just for those who live in houses, either — there are plenty of apartment and condo portraits as well. Take a look:
1. My absolute favorite: home portraits by Rebekka Seale. She seems to make every piece whimsical and happy. Custom portrait, $150.
2. For something more abstract, see work by Su Owen on Etsy. Custom portrait, $100.
3. Another fabulous find, House Love Shop incorporates custom details. Custom portrait varies.
