You have to listen to your inner voice, run background checks and get recommendations.

Not all buildings disallow amenities so check with your Realtor.

Anything over 30 days is considered a long term rental, so you will need a lease, do background checks like you would with a LTR.You could do well with that strategy. 

I would recommend you check out BizDev Mastermind, Brian Hughes.

You can also check meetup.com or search Facebook for real estate investment groups, clubs, or meetings in your area.

You need to develop and stick to a much more stringent screening program to avoid this becoming a regular occurence.

Check in with him on the mortgage side first, there are a lot of creative income programs currently, including a P&L statement for entrepreneurs which could require less down..Good luck! 

@Henry ZhuI am not familiar with that market, but check out furnished finder for stats on your market!  

---They can defer capital gains and still have cashflow with no headaches.Try negotiating 5%/$12k down so you still have funds for deferred maintenance.After 3-5 years, you can refinance to pay seller off.CHALLENGE: you better check everything out financially and with the properties (well inspections, etc.) to make sure seller is not dumping their problems on you.

I own a business checking account to manage rental income.
