If you have natural gas to that spot for a tanked unit, swapping to a tankless is cake.Insulate the garage door if that isn't done.If you are local and handy, you can do a DIY mini split in there for under $1000.

Maybe not directly but they'll shut off the gas to the house.

If half of the 24 units I own paid late, and I charged 10 per day, thats 120 dollars a day, but then the cost of gas to drive to each property, where and tear on your car, and just the hours wasted of your time that could be used on other money making endeavors, makes hand collection of rent poor use of your time.Thats why I'd rather collect rent online.

My personal experience is that I just switched from propane gas to natural gas on my own residence this past fall for about $3.5k and It's AMAZING.

When I originally inquired about getting gas to the house and a meter put in they told me up to 2 months.

I know people who have converted from gas to electric baseboard heat.

In my opinion tankless is more expensive and use more gas to run.

Plus it would take money for the ink pens and the paper they write their contracts on and money for the lunches they will eat and the gas to drive to the meetings. 

I'll go to the county clerks office and get 25 leads for 25 cents a page plus the cost of gas to and from. 100 leads for 300 bucks a month?

On some deals I know they are almost a sure thing and I experience ease although my foot is always pushing the gas to the max to get it done.Others are the most terrifying experiences.
