Down payment should be about the same (20% on a buy-and-hold) but you'll see an additional $3-$6k on average in CC and the ability to keep it off of your DTI/Personal credit along with hopefully no more hard inquiries on your credit (many lenders will accept/perform a soft pull).

I’ve invested relatively small amounts in “flyers”, and because the invested amount was small in relation to my overall portfolio chose not to perform a thorough due diligence.  

RTR advertises high returns as part of their marketing strategy, but the reality is that many of their properties do not perform as well as advertised.

Not sure why that happen, however the best way to screen a potential tenant is to see how they have performed in the past. 

Owners mistakenly ASSUME all PMCs offer the exact SAME SERVICES and PERFORM those services EXACTLY THE SAME WAY, so price is the only differentiator – so, they often select the first PMC they call or that calls them back!

Haha, but you know what they say - past performance is no guarantee of future results. 

Or are they performing some sort of arbitrage and they are not the end buyer.

Put together a spreadsheet and compare the performance of the subject property if you keep renting it as is for the next 10 or 20 years versus if you rehab and refinance.

And, past performance is no guarantee of future results. 

In the end a solid turnkey company will still be able to provide a performing asset to their investors.
