House hacking a 2-4 unit property with FHA (3.5% down) or Conventional (5% down) can be a smart way to start, while DSCR loans or partnerships can help if you need alternative financing.

After several weeks the warranty repairman met my sister and looked at the HVAC unit and said there was no leak.

We have taken over LOTS of occupied units with under paying tenants.

The vacancy is the commercial unit.

Quote from @Jeff Roth: Hi Lina from Texas-Congratulations on your interest in investing in mid-term rentals and you are wondering how and where to get started.I get this question frequently from investors.Sometimes and investor is looking to keep their property cashflow positive as insurance and taxes have squeezed cashflow by turning units into mid-term or short-term rentals.First off, ideally, the property will cashflow as a long-term rental should something disrupt the mid-term rental model.You will also want to have the property be near where there would be a demand for mid-term rentals (hospitals, universities, research centers).Monthly rents for mid-term rentals are about 20% (+/-) higher than unfurnished similar long-term rentals.There are property managers that will manage mid-term rentals for you and I always advise my clients to use property managers to keep their investment as passive as possible and for compliance issues related to Fair Housing Laws and local regulations.To Your Success! 

When I first got into syndication, I started with a 37-unit property.

If you can beat the ROI you're getting on the SFR, then do it.Otherwise, why can't you buy a 2-4 unit with a 3% down FHA loan?

How many units is it?

Quote from @Mason Jacobs: @Marios Andrianos Im a private lender and would refi you as long as you had a LLC and a few other small things, if you are investing in the United States are you trying to use a bank in Greece for the US property? 

@Matthew Posteraro go with as many units as you can!
