Finding a quality property that cash flows (if that is what you are seeking) will be difficult. 

We also use flood-stop supply hoses for our washing machines.Are there any other products out there?  

I am not looking to take equity out against my house, and my other 2 rental properties are already going through a cash out refinance to pay for renovations of a fixer upper that I am buying.

My plan is to sell my current house which will give me around $300,000 and in the next 2 years me and my wife will save another $100,000 which come to the total of cash we have in hand is $400,000.

With the SRT we restock basic supplies between guests - toilet paper, paper towels, shampoo/body wash, laundry detergent.

We had to wash the walls, then prime and paint them, as well as washing and painting the cabinet faces in the kitchen (building is in a C neighborhood).

I will cash buy as I don’t really like their financing and don’t want to deal with currency fluctuations causing my payment to change month to month. 

They didn't have access to BiggerPockets where they could learn how to calculate cash-on-cash, ROI, ROE, or print reports with colorful charts and graphs.Earn money.

If you NEED cash flow to invest in real estate you’re not ready.

I know in my state, we have to accept cash payments.
