I would want to have at least one additional property going simultaneously, maybe 2, with some cash flow although those would have to be financed pretty heavily as there isn't a ton of cash to invest in all 3 (unless we intend to live in some rough areas).

My goal is to relocate to Florida's gulf coast and build a buy-and-hold RE portfolio commensurate with my current salary, while simultaneously reducing living expenses.

They used to do them simultaneously with the close.

don't exclude the possibility of doing both simultaneously (rather than alternately or either/or)there are some really good points made thus far in this thread:  i especially like the 'good neighbor' thing and I'm a huge fan of house hacking.Imo, @Melroy D'Souza has the same short answer/advice that I do.  

She advised me that she would not/could not do a simultaneous DC, and that it would have to happen 1 week apart as she, technically, "should not know" about premeditated double closing.

can you do a simultaneous closing with an attorney and use buyer funds?

The exception is when several of these improvements are done simultaneously, otherwise known as a renovation.

I met with the loan officer before I even saw the property to see if I can get financing by simultaneously refinancing my house while purchasing the investment.  

If you go over 6 total mortgaged properties, and close them all simultaneously, than you will have to have a credit score of 720 and slightly higher down payments.

You could buy sub2 while simultaneously paying the past due amounts.....IF the bank is willing to accept just the arrears at this point to bring the loan current.
