New to real estate

[Murilo Da Mata]

Hello, everyone - feeling very greatful for finding this amazing community. 
My fiancé recently had a house gifted to her and we are finishing the rehab process. We in california and most likely we are going to refinance the house. The house is worth about $1.6mi - we considered selling the house bc it only rents for about 6k usd/mo but if we sell it we going to pay too much in capital gains/taxes as her GMA paid about 170k for the house. I’m just not quite sure if it would be better to brrrr, fix and flip or build to sell. I have been considering a mix of brrrr and build to sell, I don’t really have any experience with real estate so feeling lost about where to start but very excited to get things going. I spoke with a realtor today and she was very nice and seemed very hands on.
