Boy I constantly see people here asking about wholesaling, how to find cash buyers, how to find motivated seller leads and questions on what mentoring system to buy for wholesaling.
I don't mean to crap on anyone's w...

While there isn't necessarily a foolproof way or single way to handle this, your girlfriend should consult with here manager/broker/mentor. 

A friend and I are trying to create a fool proof way to automate our Airbnb cleaning schedule.

We've almost been operating in a fool-proof market, it has been more difficult to fail since we've had the safety net of huge appreciation in as little time as a year.

Make sure you have aligned interests because if mortgage broker doesn't get paid until closing you bet they are going to heavily vet any lender to work with otherwise they get nothing for their time invested.These tips are not foolproof but help weed out the fraudsters.

The eviction was the only foolproof way of getting him out for good.

So networking with other investors in your area, while not foolproof, should limit your risk in this area.  

And while not foolproof, a realtor recommendation usually helps with finding a better one than we can find for ourselves.  

(and, unfortunately, I don't think anyone has a fool-proof answer).Although nobody knows for sure what the market and values will look like in 6, 12, or 24 months, the one thing we DO know for sure is that the market is changing rapidly, and rates will likely continue to increase at least in the short term...Personally, I would be very conservative with ARV estimates right now (and, quite frankly, I personally wouldn't pursue any strategies like flipping or BRRR'ing that require hypothetical future values to pencil out--that's a bit too speculative for my tastes, given the market.)   ...however, if the property was a home-run cashflower right out of the gate (with no or minimal reno), and I knew I could easily rent it if my BRRRR or flip plans fell through, then I might go for it...but, I'd definitely want multiple exit strategies, and would not want my whole plan resting on hitting an ARV, or being able to refi into a hypothetical future rate...Good luck out there!

I had one of my investor who got hooked up with a shyster in KC and that guy just QC the property back to him but the title company would not insure it.. so he had to then go full blown foreclosure route to clean the title up.. when he could have done a deed in Lui.. but he was a novice and did not really understand until I helped him through it.So any-who foreclosure route is fool proof..
