I have done many 1031's Selling cost money you also may encoure a fee for paying off mortgage so soon. Its a very hard time of year to rent. Look at comps see if what the house should be listed for and then slightly rent for less. Also maybe the property manager is the issue ? If you 1031 into a new property there are fees again, mortgage cost rehab closing etc so sometimes your not much head. I would only sell if the actual property was a issue like the area was bad or the property had too many work order issues. Losing $300 per month is a lot but if you can get it rented and possibly rent go up a bit then if might be okay. Your also paying down the mortgage each month so some of this $300 if not all is going to the loan. If it was me and its was just a rent issue I would save all the extra work by selling and finding something new and just hold. Over time you hopefully should get the extra $300 and maybe even more down the road to even out the losses. In regards to sell now the prices are going down next year, people said that at the beginning of covid and they did not. Its too hard to time the market so do use that as a factor. Even if prices dropped in lets say 3 year and you decide to sell then your 1031 so the new property would have dropped too. The only time a price drop matters is on the cash out i guess. Good luck maybe trying to do a light reno to the property will attract more renters and maybe get a few bucks more per month
