Will it be fairly easy to sell later?

Clearly there were missed maintenance issues in this case, but I would still instruct your PM (or future PM) to make it a requirement that all prospective tenants tour your properties first before processing applications.I’ve even had tenants sign Sight Unseen / As-Is addendums and later be unhappy and still want to break their leases.

Sure it will cost more and take longer but consider it the price of your education.Other than that your option as others have point out is to find the money to finish it off the books of the hard money lender, sell it or refi it and pay off the lender and move on.

Do you sell your mortgages?

Owner is motivated to sell and says expenses are $2300/month (includes lease rent 1700+600 in electricity/gas water included in rent).

Marketing is key and also leaving some meat on the bone for another investor helps sell it (unless it's fully turn key, which can be attractive for a 1031 exchange specifically). 

My only concern is if I have to sell the property, I'd have this huge loan that I would have to tack onto the price of the property?

Spill the beans.... what did you get it under contract for, what did you sell it for, what was your profit? 

PS - if you are looking to invest out of state, my best advice is finding an investor friendly real estate agent and someone who invests in real estate themselves because they can plug you in with their systems, processes, real estate team such as GCs, PMs, lenders, etc

My income has dropped significantly bc I chose to sell my business and take a more relaxed job so I would stop killing myself.
