I think the best and easiest way to get started is to use a servicing company.

Is there anyone in the BP universe that has added solar panels to a house to decrease utility costs? 

Hey mate,Sorry to hear about your troubles but it's not too uncommon.I've been in the turnkey biz for 10+ years now and have often been called the "bad guy" as we only sell to investors looking to purchase with cash.Many believe that because we only accept cash buyers, that we inflate the properties price which definitely isn't accurate.Quite on the contrary when looking back I feel that we under sold them lolWe can justify every one of our property prices with a CMA independent of our in-house sales.Whoever believes that financing a turnkey property makes it safe is wrong.Most turnkey providers or affiliates push the financing model (Even in today's high interest environment) to make more sales.They have "in-house" lenders or community banks that they establish relationships with and promise large volumes in loans.This in return get's rewarded with various favors and many are easily able to manipulate appraisals.Having flipped over a thousand properties, I know how easily an appraisal can be manipulated so for anything reading, "NO", financing a turnkey property doesn't necessarily make you purchase it for fair market value.To answer your question:When S#%@ hit's the fan like it did for you with this deal, I personally would always look to cut my losses and move on smarter and more experienced.Granted, over the years I have witnessed many investors buy 1-2 properties from my company and expect miracles only to get disappointed. 

For example, working with insurance companies who's clients home has been destroyed (fire, flood, wind etc). 

@Arwin NassiriI think tulum is a great market if utilized correctly.

You can absolutely use a credit repair company to challenge everything on your report. 

We are all in for about $60k (not counting utilities). 

Since then the company decided to overhaul (and temporarily close) their business and sold off the properties, and investors got a payout from the sale proceeds of the properties they invested.

There are lot of companies you can use to do them; Red Star, RentPrep, Cozy, etc.
