Has anyone on here done something similar and remember the cost or have an idea of what pricing should be (ballpark)? 

Could be an absolutely gigantic cost and ruin the deal for you, or could be small.

If you’re even considering this look around for something with a $10-$20k deductible and see if you can cut it in half.

This takes seconds and costs pennies to run the reports for hundreds of thousands of loans.

The barrier is the additional complexity - now you are operating two sets of books, and filing two tax returns, and have more operating agreements, more state registrations, etc, need to manage cash better, need to keep in constant mind that your rents need to be a supportable FMV, which may require getting third party certification on your rents so that in the event of an IRS audit, what you have done is supported.In short...the size of the project, and the taxable income, need to be of enough scope to make all the additional costs and annoyances worth it. 

They can’t lend you more because if they have to foreclose it will cost them at least 10%.)Then you want to take that $300k and get a loan for another $300k with that $300k to buy your dream home.

@Rania MutumheHouse hacking means turning a place into a rental space, which calls for fix-ups, planning costs, and expert help.

Hey Claudio,What Robin said - it does depend on what strategy you are implementing!

So how much did this cost me to get involved besides an awful lot of time?

It depends on how much the NY house will sell for vs how much the TN house will cost.
