Sounds like a great adventure to me.
IMO the space isn't a big deal except maybe having the dogs with. I can say we took our dogs everywhere camping (tent) with us, 2 or 3 big dogs in the back of the pickup. Was great til we had a kid. Dogs only go for rides now to the vet! Did just make a trip to AK with 2 dogs, the cat, and kids. Week or 2 like this no problem. Year or 2, eh would depend on the dogs.
The rest of the plan sounds solid........and fun! Go for it.
We've rented out multiple homes around the country and honesty we are about 50/50 for tenants. Didn't have anyone who stole appliances and punched holes in the wall and haven't had anyone who fixes everything like it's their house. But all our tenants have been long distance. With you having the ability to keep tabs on them and your house, it will be much easier. Not a guarantee, but easier to control a bad tenant.
Tax wise, there are some advantages to being a landlord , IF you don't make too much to qualify for the deductions.
Have fun!
