The STR can possibly be more cash flow but depending on the market it's getting more and more strict every year with that.

These syndication can provide an 8%+ cash-on-cash return - providing investors monthly cash flow - and a 15-20% IRR over the length of the project.

Providing all the necessities for cooking and cleaning up.  

No tenants or cash flow.

I have experienced cash flow anywhere from 10-18% with so much more to offer.

Either option would cash flow around $300/m. 

It looks like the pump is connected to an ABS (plastic) drain pipe going into the ground and that like should not be clogging, at all, if the pump is working properly.Every plumbing system with a pump needs a high number of clean-outs to access the pipe so you can clean the pipes with the proper equipment.

There should absolutely be no hesitation if the property cash flows on a long term basis.

Places that need new flooring, paint, a deep cleaning, some yard work and so on. 

I think of if I had to buy my first house two years ago when I was just about to get married, having a variable income with no cash flow supplement, it would be a dramatically tougher situation.
