It seems like every house we've rented in the Kissimmee area is owned by people from the UK. They have all been wonderful to work with....helpful, courteous, communicative, etc. I don't think you need to fear renting a house from the UK owners at all. I think you will be able to tell after exchanging a few emails if someone is trustworthy and professional. Don't let their nationality scare you away from renting. Everyone I've dealt with has a local management company to deal with your questions and concerns and they've all been great to work with too.
