Financially it is not a stretch for my sis and broinlaw without having my parents contribute. 

For whatever reason, I woke up one day, felt like I could achieve financial independence and create an early retirement.

I may be able to get a financial partner for this balance but if I cannot what are your thoughts on using an additional loan?

You’ll need to take the financials and put together an Offering Memordandum to present to investors (usually takes me a few days).  

Regarding damages, if you were able to get some sort of financial judgement, the chances of collecting on it would be close to zero.

I'm happy to connect with you to answer questions and help connect you to other in the network to expand your sphere of influence. 

They stated their starting price; as I asked for financials they sent me their tax returns I asked if they have anything more specific to each unit and etc.

HOA board members are generally unable to separate the "insult" of having to carry their neighbor financially from pure business decisions.I think your best bet is to work your deal so that the HOA is paid off in full. 

These are all things that would influence how you would structure this.For example, if you're looking to sell your brokerage soon, I would recommend carving out your commissions from the overall company income. 

We look forward to posting several success stories here and helping others in this journey to financial freedom.
