Granted, it's been probably 15+ years since I did an installment sale, so I'm definitely not very fresh on this. 

I know most folks recommend start fresh with your own tenant but if the tenant has a good record this would minimize vacancy.

To put it in perspective, we lived here for 4 years and my mom still hasn't seen the house... it was just embarrassing. 

- These are all just basic examples of things to consider beyond comparing the cap rate.This may help put it in perspective: https://www.biggerpockets.com/member-blogs/6405/80732-5-simple-formulas-every-buy-and-hold-investor-needs-to-know

As an out of investor wanted to get some perspective from your wisdom: I've got occupied SFH, and my Tenant is not paying: I got 250$/1090$ for Mayand 150$/1090$ for June.

I can't speak to the specifics of the installation or solutions for that but I thought I'd give my perspective on the answers to your questions.What could you have done differently? 

@John K.So I think I see the issue - it is the perspective point of view.

There is risk with leverage, and your cash flow will be less, BUT from an return perspective, the less money you have in a deal, the higher your return will be.

Some of the podcasts is more advance for my level, I will definitely look for newer guests to learn about their journey, experience and perspective.

I think it'd be worth trying FSBO for a couple of months since you'll prob get your best offer when it's "fresh".If it doesn't work, take it off the market for a month, then hire someone to re-list it so it'll look relatively "fresh".However, to get access to the listing services, you may need to go to a place like Redfin (not an good/bad endorsement of them).
