Don't want to be stuck with a stall for weeks then non-payment.Does the act of signing make it a valid lease or does the consideration/money need to be delivered to be valid?

AXA is an insurance company and much of their retirement products are annuity focused, which may or may not be what you need / are looking for.  

Many on-line vendors have ridiculous shipping fees or will NOT credit products that fail.

My own two cents from the world of tech entrepreneurship, the fact hat you have demand may stem out of your ability to sell, not necessarily from a great product. 

You'll still have to validate your numbers.

@Bryan Richard  You might be able to refinance into an alternative loan product.  

What are some good tenant screening apps that will provide complete reports? the one i am using seems to return less than helpful reports. (not going to name it)thanks!

Then, when it’s time to purchase the third property, you could refi out of the first FHA loan (if you have enough equity), and then use your FHA loan again, or use a conventional loan product. 

You want to reno for the market.....so you want the best product at the best price.   

@Eli Sorey - I think that this answer will vary depending on the production of the agent.
