Well I wouldn't invest so far away from where you live. I would invest in my own area to keep it local. It is easier to control and manage so you won't have to add a property management company that will suck away any profits you have left over.
Occupancy rates is one factor but another is the RENT ROLL. Call a property management company down there that handles many rentals for the area you want to buy in. Ask for the type of property you want to buy say 3 bed 2 bath how long it takes on average to rent out and what range. Ask for lowest to highest amounts. Base numbers off the lowest amount to be conservative and factor in 1 to 2 vacant months out of a year for a buffer.
Now you want to run your numbers with a mortgage broker to see with property management that will screen tenants properly and collect rents what the break even point is after mortgage,management,taxes,hoa fees,landlord insurance,etc.,etc.
Then you have to decide are you buying for cashflow or are you buying for upside later on??
When the markets were hot people cared little if they cash flowed because they could refinance out cash with the rapid appreciation. Now that markets are very slow to recover it could take years to see a substantial uptick in prices. Knowing this you want to in my opinion break a decent profit every month and set a reserve fund for vacancy loss and damages,repairs from tenants.
Now if I had a lot of money I would invest in commercial real estate. You can buy a developed parcel from a distressed development that all that is needed is to build the structure. You can get killer returns when the markets come back in a few years and would only be paying taxes on the land. You could also buy a small strip center say with 8 storefronts. You can make much more cashflow and easier to manage under one roof.
Unlike multiple homes where you always have a repair needed at a different location.
