There's half a dozen or so heaters so as long as a couple near water sources are turned on, it should be fine.

However, you can cross reference the data with Google street view or similar source.

@Michael Noto, @Mathew Allen, @Ryan Luby, code requires the following:Must be at least 70 sq ft, minimum 7ft in each directionCeiling height of at least 7ftDirect access from a hallway or communal space (not from another bedroom)Second means of egress; either a door directly outside or a window at least 20" (H) x 24" (w)Proper lighting and ventilation; usually window(s) that is at least 8% of wall areaAt least 2 electrical outletsPermanent heat source that can maintain 68 degrees (space heaters don't count)Curiously, closets are not required by code, but a generally expected by tenants.

Lastly, your best source of vacancy data is other hosts as others have mentioned here.

All HML's are not created equal.Some of the nationwide lenders do a good job, but may hedge on the overall value to keep themselves in a safe position.Local private lenders, may be a great source just starting out if the properties are local because they are familiar with the local market and they can act quickly based on the deal. 

Hi BP communityI’m Aviv Dahari from Israel ,it was just the beginning of 2019 and I had this filling that something have to change , I don't want to work like this until I'm 60 there got to be another way , then by a miracle BP shows UP , and we became best friends for life .So in the past year I have studied , listened and basically learned every little thing I could get my hand's on about real estate from BP and other sources and looking forward to learn more from all of you , but the TIME has come to take some massive ACTION and live life by my own terms.My focus this year is to INVEST in rentals in Warren ,MI ,I would love to connect and work with this amazing community  ,Hope to hear from you  

I ultimately decided to move away from SFH’s because the amount of work required to continue to scale wasn’t feasible alongside a full time job.Investing passively via syndicates opened my eyes to how I could benefit from real professionals sourcing, acquiring, doing due diligence and managing my asset all without any ongoing time commitment from me.

I need to remember that I work in a world where rent rolls as presented are for the most part close to actual, and market information sources are widely available to verify reported rents.

If you are W2, and either salaried or consistently working 40 hours/week, your tax returns typically will not be used to calculate your income from that particular income source.

Been checking out a number of data sources recently - some paid like neighborhoodcout and quantmaps.
