Brrrr or flip help me decide

[Jon Wright]

I have a property I have been rehabbing for the past couple months and the finish line should be crossed this week. I will have about 60k in it and could probably sell it for around 90-100k. The house was completely gutted and has all new plumbing, hvac, cabinets, appliances, flooring, water heater. Literally like new construction on the inside. The house would rent somewhere between 650-700 in a c+b- neighborhood. I have another house under contract to buy for 46k that will rent for the same as the first house. I’m torn between keeping and renting the first house and getting a mortgage on it to buy the second house or selling the first one and getting a mortgage to buy the second and use the proceeds from the first to roll into the next flip. I’m sure there are a variety of opinions but some different perspective is what I’m looking for. Thanks in advance.
