Ariel,
I would be honored to discuss with you the actual numbers, once I have the address. Depending on the exact location is the said property, some markets are seeing as high as double digit appreciation rate thus selling might be the most financial benefiting play. In addition, when interest rates decrease in more favorable rates from the FEDS, there will be more buyers looking to diversify (buy). Generally speaking, the SFLA market, is a great play for both appreciation and cash flow. I have clients that flip, STR, develop, etc and all investment strategies varies based on preference. I provided asset management and property management to local and domestic clients. With all that you stated, I would highly advise to sell. With the potential NET of the sell you could, 1031 into a larger asset (MF, several homes, portfolio) and spread your risk over these newly acquisition. I would be honored to discuss further in details and potentially earn your business.
