For 30 year fixed based on property cash-flow, max of 70 LTV, rates in the 5.25% - 6.25% range for most -- again depends on the scenario a bit, it could be higher/lower. 

Other homes would be expected to be in the $70,000 - $100,000 range for these same components with the balance of the mortgage held by a bank.Below are actual revenue, expense, and NOI numbers for this home which we would use as a model for further acquisitions.Property Management is high, it costs a bit to manage the placement of multiple tenants, handling of disputes, and collection of rents as well as mange the cleaners, landscapers, and handymen.The 2.5% for maintenance, and 5% for capital expenses would be variable but should not be much higher than 5%.

Specifically, I want to house hack a duplex in the central Phoenix or Tempe areas in the < 500k price range. 

(Holding costs and selling costs would come out of the net profit)Price ranges would be around 200-300k is pretty average for my market.

Not sure what the rents are like around there/what range of people are looking for regular long term rentals in that area.   

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.
