My intentions is to flip the house as soon as possible, and I thought that selling the house and use the money to reinvest it will be enough to avoid capital gains.

Does anyone have any ideas or suggestions to what I can possibly do to gain ownership?

Recently (last few years) time has not been an enemy as RE pricing has been appreciating higher than the cost to hold, producing net gains for holding longer.

Finding a property management company that you can trust with your investment can be a weight off of your shoulders and provide "mailbox" money to you without you having to lift a finger (except for when you have to grab that money from the mailbox).The cost of property management services varies, but any great trustworthy property management company can outweigh the cost substantially by providing you with time-saving services that handle the day-to-day operations of owning a rental investment property.

Remember that when you are buying/furnishing a STR, you can sometimes gain value from things that a typical renter might find a turn-off.

The cash. you take out is taxable but the rest of the gain is sheltered in the 1031.

Because I have NOT lived in my house IF I go to sell it right now I will pay capital gains tax.

Great first time buy with knowledge gained on rehabbing and renting.

I am enjoying browsing the archives to gain knowledge from you all, and I am excited to be a part of this community! 

Primary residence gain is not taxable (to certain limits), so when you convert to investment property, you convert at a higher basis.
