Given that you and your spouse have great credit, that would be a compensating factor in your favor. 

Maybe I am not doing hosts a favor by letting them know when we leave.

You would make more money putting $250,000 down on 4 properties then buying a single 1 million dollar property if financing terms are favorable.

Do yourself a favor and build bench strength by adding an investor focused realtor to your team.

You can refinance through a commercial/portfolio loan rather than a conventional Fannie/Freddie one.The rates/terms will be slightly less favorable but just underwrite the deal accordingly and see if it still works.

I've used them in the past on multiple properties, and depending on the property type, FiCo, and any compensating factors in your favor (reserves, seasoned investor, F&C properties), you can get really great rates.

Many more options and favorable terms. 

Get your finances in order and use an old fashioned conventional.

Can you provide any examples of what a tax-favorable investment might look like to illustrate your point?  

I’m happy to help where I can this time, but at some point in the next conversation I’d like for you to return the favor and let me help you sell your house/buy your house on a professional level so that I can earn my living too.”
