We have transitioned one of our properties just recently to us owning them and using cards.

hahaKeep the dream alive and wishing you much success

I took advantage of that feature and sent some lease option cards to a select audience north of my usual territory.  

Is there a recommended option for washer/dryer that doesn't require coins/bills but instead takes phone pay or a card, so that both tenants and prop managers don't have to deal with coins and bills?

They are not cheap and obviously require some kind of cellular plan, but I was able to get them to work using Mint mobile (you need a phone to activate the sim card on first, like an old iphone) Ive had 3 of these up watching a property in Cleveland, OH for well over a year, and Ive only had one issue where I needed to go check on the camera itself, (the plug for the solar panel came disconnected and just needed plugged back in) This camera in particular is nice because its actually 2 lenses that capture the full 180 degrees, so one cellular plan for "2" cameras.

You can make sure to get 10% off coupons from usps moving or buy gift cards at 90 cents on the dollar (I get them as credit card rewards) to stack up the best discounts.

Just be careful with mentoring programs and leave your wallet and credit cards at home when you go to the seminars.   

good place to pick up cards.

I asked them they sent me multiple pages of detailed bill which is again having charges that I don’t even think in my dream.

I was bitten by the Real Estate bug awhile ago and after listening to the podcast, I am finally trying to take the steps to hopefully turn this dream into a reality.
