Moving and seeking advice

Hello everyone,

I'm Kat and we (wife.kids) are planning on moving to Siem Reap in September/October of 2019. We are researching Visa options and are hoping we can extend once we get there for 6 months to a year.

My questions are more geared toward day to day living.

1. How hard is it to find an 2 bedroom apartment or home with twin beds? Will a landlord switch out for twins?

2. How much should we reasonably expect to pay in rent for a serviced apartment?

3. We have a dog, a small 7.5 one. I'm seriously leaning toward leaving her here. Am I going in the right direction?

4. Visa wise, if we own our business or work remotely can we use that for the  business Visa requirement?

5. Neighborhood recommendations?

I think that's all I have for now and if my questions are redundant please delete and point me in the right direction.
