We recently bought a duplex and are almost done remodeling it to get us to where rents need to be for that A or B class tenant.I personally find that due to long term buy & hold in this area, it’s just enough to break even for first year or two.  

Be prepared to start a lawsuit.2) File a complaint with state's Board of Realtors3) File a complaint with state's Attorney General's officeSince these are unlikely to be permanent solutions, you'll also want to start searching for another PMC.Recommend you speak with @Russell Brazil

I would say a complete home remodel definitely has challenges.

You've had lots of investors, nobody is complaining, you aren't over hyping your past deals but they are easily verifiable and have the proper filings.

I wanted to bring in more houses, I wanted to take pictures with the guys and our remodeled houses like trophies and make media to bring in more sales, perhaps joint venture with other investors and grow a really strong powerhouse of a team and take on tough, challenging places and really beautify an old neighborhood.

If they claim not to have seen your offer you file a complaint with the local board of realtors and also with the state's real estate commission. 

Guillaume I would not make too many LLCs unless you are aggressively buying property since you have to file taxes on every LLC.

I still tried to reason with her to see if we could repair this, but she hired a personal injury lawyer (who happens to be a cleaning client of her) to start emailing me demanding I give her $125,000 for her 1/2 of the business, or else they are going to file a lawsuit.

They take weeks reviewing things and won't call you or tell you when they have reviewed things so you are constantly calling and then waiting for them to find your file.

I'm still spending money on capex items and remodels plus getting rents to market so I'm in the "stabilizing" phase.
