I would strongly encourage anyone reading this post who has used that site as guidance in the past to do the same.My normal practice when determining market rent is to use a range of factors, that include GoSection8 data, the local housing authority's published rent matrix, information from Rentometer, from Zillow's rent estimator, and the MLS.

You can use Realtors directly as well, but the expense will likely be in the same range.

That is possible in your price range but it might be further out than you want. 

Additionally, I would say realistic ARV would be in the 150k range.

I'm working with some JV partners now to try to find something in the 10-30 unit range.

If you sold, you could look into doing a 1031 exchange to defer the capital gains, and use the ~$450K proceeds as a down payment on a MFH in the $1.5 - $1.8M range which at a decent CAP rate would bring you much better returns than what you're getting now. 

Within our price range.

If you are utilizing a channel manager on your own, I recommend VRBO (90+ days out) for long range guests (older clientele, who typically have more time and can plan our their stays further in advance) and let ABNB (0-90 days out) bat clean up. 

I think these are realistic numbers: neither a fantastic property nor a terrible one (and notice I've set the manager's fee at the top of the usual range).

However plowing, shoveling, and salting has not been an insignificant cost for us, probably in the range of 3-5%+ of our gross income (depending on how much salt they really use).
