Find out what financial problem you are trying to solve in the short term until your able to get to more "long term" problems that real estate helps with 

With your primary residence, things can be pretty straight forward in terms of splitting mortgage interest, real estate taxes etc. on your returns.If you go into a rental property, there are a lot of considerations to think about.

I think this will be the short term realization, and anyone that did not wait on the sidelines and jumped in with the intention of a short-term re-fi might have to tap out. 

If you were renting to an only a couple as a long term tenant and they beat each other up (domestic violence) your liability is minimal.  

Might be a diamond on the rough if you can fix it up and then long-term rent.

I'm not a fan of selling a property that is performing in order to solve a short term problem.

I recently launched a short-term rental (STR) business in Gainesville, and I’d love to hear from other investors in the area.

Seller Financing / Sub-To: Take over payments or negotiate terms with sellers to minimize upfront costs.  

Knowingly buying into the red just because of financing terms is a very unhealthy way to invest.

Some lenders offer creative solutions, like a cross-collateralized loan, where they use your existing equity as security without refinancing the duplex.Another idea is partnering with private lenders or exploring a second-position mortgage, depending on your lender's terms.
