Multiple Purchase Considerations

[Nate Morris]

I am working to 1) ReFi our rental for cash out (on both mine and my wife's name) 2) purchase short term rental (seller financed) 3) purchase an apartment building. 

How does the lending and escrow process work on multiple transactions and what strategy should I take? 

Must these transactions happen sequentially? Can my wife's take one loan while I take another?
