That being said, my sample pool in the main scheme of things is pretty small (probably 15k customer pulls or so).  

Let me know if you want a sample.

Of course they don't get the house, but it's a fun exercise for them and I did it for free.

If you are just learning to code, it could be a great exercise but it probably wouldn't be the first way I would choose to spend my time. 

Using an interview sheet with prepared questions will help guide your due diligence and note taking and could include questions on their screening process and criteria, rent collection process and enforcement of leases and late fees, eviction process and timing, monthly settlement process with owners, management software they use and it's functionality, owner's reporting, the maintenance request process and follow up, contractor depth, contractor pricing, commitments on turn times, their vacancy statistics, # units under management in your asset class and in your sub-market, requirements for renters insurance, whether or not they work with a collection agency....the list can go on based on your specific needs and these interviews can take a while.You will want to review their leases, management agreements and sample monthly reporting.  

There will you find numerous sample's..

Since this is short term flip they will be prorated at closing and I only did a 6 month policy for insurance.Hoa is 958 a quarter which includes the following: Accounting, Conference Center, Exercise Room, Gated Community, Ground Keeping, Internet-WiFi, Management, Mini Golf, Pest Control, Playground, Pool, Tennis, TV CableComplex includes: 11 pools(5 heated), shuffleboards, beach house/café, mini golf, exercise room, tennis courts, playground, WIFI, cable, pest control, termite bond, trash, ground keeping, property patrol, gated community etccost to own:Power $125/month Water $80/monthGas $40/monthshort term rental Insurance $4000/year Current taxes $1776Over head is $2615 a month.

If you think you might lose money go through the exercise of what that would look like.
