.- Put Upward pressure on real estate operating costs: Increased costs for raw materials and supplies, and the likely increased costs for labor involved in many real estate related CapEx and maintenance projects signal the risk of increase in costs for real estate operators.If there is no impact on near-term supply, a modest slowing of inbound (illegal) migration, more reason to believe that the cost of many goods and services will increase, and real reason to believe that inflation triggered by something other than an increase in the money supply (namely the cost of specific goods and services that are NOT housing going up, which comprise the CPI) will force the Fed to raise rates, this, on the whole, is not good for real estate investment returns. 

Quote from @LaTonya Clark: I can cancel the deal with no problems. yes, I feel like I am forcing this bc I want it so bad.

Is my only next move to threaten to sue the HOA to force the door?  

In a way, I think the BRRRR process is really the process of "adding value" to a property and then pulling out that forced equity as much as you can.

I was forced into hiring an electrician and plumber, the two things i was best at doing. 

Never force a deal—if the numbers don’t work, walk away.

You can also trade up these properties quicker into other properties where you can force equity.

It forces me to call VRBO to reset the account but luckily they are easy to get a hold of and fix.  

If you do a forced air with ducting, you could do a heat pump.

.- Ask the attorney if your aunt & dad need to authorize lien, or just aunt.2) Understanding your options to force payoff of the lien.- Ask attorney how you can enforce collecting on the lien when you need to.3) Getting full control of the property, while allowing your aunt to keep her ownership.- Have attorney draw up a contract to do this.Suggest you offer your dad some cash, now or in the near future, to motivate him to transfer his ownership to you.It may not work out, but you will learn a lot either way!
