I would suggest that you focus on building your team.

Any suggestions would be helpfulwe will hire an expert to manage this transaction.  

Also, exploring online platforms like BiggerPockets can connect you with professionals experienced in various locations so I highly suggest that you keep connecting with everyone in the community.

@Kyle Swengel, I suggest you look into the negative effects of deprecation recapture, as well as if the losses generated from the cost seg you can even use to offset significant income.

My suggestion would be to send the security deposit claim for the anticipated refund minus what you anticipate the bill will be (historical average plus some padding).

However it's not as simple as was suggested here earlier.

It all depends upon the total cost of construction, based on that your monthly fixed cost/mortgage will come into picture.You cannot rent too far from market rate, essentially you should have some spread between mortgage(construction cost) and rent to cover for cashflow, vacancy etc.I would suggest you to keep the selling it out as your second exit strategy if renting is your first one. in that case your construction cost + selling cost cannot be more than market price of new construction.You can also try to reach out to developers to give them a piece of the pie but then you will have to sell for sure.

. :) Surprisingly, the HOA has no lease minimums, my real estate lawyer confirmed when I bought there is nothing limiting me from renting it on Airbnb (which was her suggestion lol).

With one of the largest expenses on the line, I suggest the buyer truly understand the septic's health, not simply hope to pass the inspection.
