Then opendoor would clean the home, maybe paint it, maybe put new carpet if you are lucky then resell your home for $400k in a week or two.

Landbanks are more or less where municipalities go in and take properties from negligent/bad landlords who leave properties un-kept for years, take them , mow the grass and re-sell them to people who will take care of them, otherwise they get torn down. 

I do understand that if I were to resell when the tenants are in place I would need to transfer the money, but I have some small maintenance items I want to address this month and instead of borrowing the money from my bank to make repairs can I use the last month rent money.  

Is it easy to re-sell or do you think people try and steer clear from purchasing homes with CDD & HOA?

You could look more into a Lease Purchase or Land Contract instead where you are doing a seller carry scenario of sorts, then you could re-rent the property and ultimately re-sell the property. 

You may consider looking at a reverse 1031 exchange, complicated but maybe easier than financing, buying and reselling to a family member. 

Generally they are rebuilding or renovating to resell.

Flips do not qualify for 1031 because your intent when you buy the property is primarily to resell.  

Sounds like you wanna wholesale the deal and not renovate it and resell.
