Most investors I help with these, do them on properties they will keep for steady cashflow, keep organized, and to not pay so much in lender fees over time. 

What I wouldn't do is give up my day job right now, and try to do something that doesn't provide a steady income... no matter how much you hate what you are doing. 

There are no controls for the HVAC in the apartment, but we kept things at a reasonable temperature and never had any complaints.

Because of this in the downturn rent rates stay steady.

I know one can always become an agent, but sometimes that can take a while to establish and become a steady source of income.

Considering you are a business owner and that your business is highly seasonal, I would look for a property large enough to provide me with steady income in the slower seasons.

How do investors get such a steady flow of properties that make their numbers work? 

Plus, reflective and lower the temperature in the units by 20 degrees. 

If you are looking for a dividend, and steady retirement income, it is a good option.If you want the asset to continue to appreciate while paying down the debt, another good reason to keep the money in.If you find a great deal that is newer and can be held long term and is rather easy to manage, another reason to hold long term 

I personally am biased towards savannah (love it) but it has some major problems (crime) and decent steady growth but not explosive growth.
