For example for a rental with $2700/month rent with folling scenarios, how much mimum income would be considered adequate?

I once ran across a hot tub where the customer mentioned it tingled when they were getting in it .

Also look at the rental laws in the areas you are considering, just so you understand what you are getting into and whether you are OK with them or not.

The person they consider having the deep pockets. 

Also make sure to consider all the aspects you can including the tax differences. 

Always looking for great deals but very selective as we don't really need to add to our portfolio at this time - but would definitely consider a great deal. 

The only reason you’d consider a 1031 is if you have more than $250k in gains (if single) or $500k in gains (if married.).

@Tiffany Palaskas consider the refinance route as well.

Which is why you may want to consider starting in multifamily and convert them to airbnbs which is what I did for a while.Best of luck to you. 

If you offer more $ for the property than the all cash offers AND you appear to the seller to be highly qualified in the method you are using for sourcing the payment, at some point your offer will be more appealing than the all cash offers.I don't understand why you would consider a 1031 for another property in two years.
