I got 4 or 5 calls off of several mailings.

if you don't mind roommates, consider a house hack to off set the mortgage costs. if you do that, get leases signed by those roommates as it'll help your financing picture for the next property as you'll have shown the ability to operate as a landlord.  

If you are planning to hand off, I wouldn't worry about systems and processes; they will have their own they utilize.

You're better off starting with something more grounded, like securing funds and getting a few transactions under your belt.

Hire a competent investor friendly agent (one that also invests themselves) - their expertise will pay off ten-fold in helping you find the right investment property.

Ours were shut off more than they were on....

Usually those kinds of deals are along the lines of 40% off the top.

One thing that helped me as well was deciding what I wanted to take "off my plate" first and matching that with revenue goals for my company.

if you are going to add value and cashflow the Laundromat, I'd assume that having the business produce the funds from profit to pay off the owner's note would be somewhat straight forward.If the deal makes sense and the cashflow is there I'd think a cary back would be a good way for the seller to get the number they want and for you to bring little or no downpayment.

It may be harder to set off the entire mortgage payment with house hacking, but any amount that you can lower your living expense is a win while simultaneously having your property appreciate.
