Make sure to ask about including errors and omissions policy, then if something happens like a software malfunction, etc. and you cost the homeowner thousands of dollars, you have insurance to cover that.Safely or Waivo are nice to have as well, they cover damage from a guest including sheets and towels, and I think also thief.

Make sure your contract includes 'and/or assigns' language and a marketing clause to be able to promote it.

Make sure to factor in all expenses such as property taxes, insurance, repairs, maintenance, repairs and potential rents. 2.

What other factors do you consider?

I would just factor in the difference between $800 and $1500 until leases run out as part of my 'closing costs'. 

But the other factor is what you mention about investing in a "tenant friendly" state.

However, in many cases you likely won't be able to obtain by-laws until you are under contract.I would have your attorney include a specific "HOA" rider in the contract for this exact reason- It basically would require that you have ample time to review the governing docs of the HOA, such as master deed, current by-laws, current year’s budget, and last two years of audited financial statements, association meeting minutes, etc.

Be cautious of cities that aren't proactive in job attraction; too much growth can lead to strict building regulations, affecting housing value.Other Factors- Favor cities with a crime index that has consistently decreased over a decade.- For appreciation, I look for a minimum of 2.5% YoY growth in median house values over the past 20 years but I don't use this explicitly in calculations.
