For a very quick estimate to determine rehab cost when contemplating buying a property you can divide your roof pitch by 12.

The updated answer I am contemplating I did research to see what fair rent is for my unit, if I rent it out to a single family.

I do see the point though and have contemplated this selling and then sitting in an apartment waiting for a crash sounds rough though. 

I have contemplated the control issue too which is why I would like to have my name on it rather than hers.

Is this something you truly want to get into or is it a shiny object you are contemplating because you found a backer?

Theft, assault, domestic violence, sex offender, burglary and whatever other felonies I might have left out will generally result in rejection.Eviction and bankruptcy are disqualifiers as well.Possession, dui are OK.

Great for you to be truly contemplating your career!

As you contemplate this and potential investment strategies, be aware of FIRPTA. 

Uncle passed away earlier this year here in CO and I am contemplating buying out the other beneficiaries of his home.

The architecture and lot of the property may favor one or the other as well.And of course, a good real estate agent can tell you what the market is for what you’re contemplating.
