If they need substantial work, Are you able to fund doing rehabs (or multiple simultaneous rehabs) if tenants leave?

The two ways to survive off the initially low cash flow up front is, in my opinion, to either save and hold (work a job and buy rental property simultaneously until you can afford to focus on real estate full time) or flip and hold (flip one and use the money to live off, flip one to afford down payment on house to hold, by hold, then repeat). 

Title agents / real estate investors in Arizona: Do I have to have money in the escrow account to pay for a property or can I use the buyer's money to close the sale (simultaneous/double closing)?

I should have included that my questions scope is in terms of a double or simultaneous close. 

So, if you are saying that you have a deal in place, and an agent (not related to the transaction) moves in on one of the principals, then you have grounds against that agent, and can report them.The only way that I have seen wholesale deals done correctly is when the wholesaler is the Buyer and either completes the transaction and flips to the end Buyer, either simultaneously or within a day of each other (the most likely to close), OR is the Buyer with the right to assign another Buyer (less likely to close). 

@Brandon Collins both simultaneously

We flip 50+ homes a year and find the whole adding/canceling insurance policy process a huge pain in the butt and very costly,  we're spending over $50,000 a year on insurance on flip properties.There has got to be a policy out there for $5k to $10k that covers a certain amount of houses simultaneously that you can "add and delete" from the policy?   

If I understand the VA loan properly, I think you may have three options you can pull off simultaneously:  1) keep your current home as a rental  2) take the cash out when you refi the current home and use that for a down payment on another investment property (non-VA) and 3) get into a new primary residence with a 0% down VA loan.

Investment real estate can produce 7.5% plus 10 or even 20% more while simultaneously providing an appreciating asset! 

Louis $250k in many inner-ring suburbs doesn't go very far, but you can get a relatively new 4BR house with 3500 sqft in Columbia, IL for the same price.I'm rambling now, but basically be careful trying to create financial independence while simultaneously upgrading your lifestyle.
