From my experience, a good rental market neighborhood exists for 3-4 months.

$150 for the yearly renewal of an existing tenantShe told me I can modify the contract to these terms, initial, and send it back.

looking at the financials and tax returns are SOP when buying existing multi family at least on the deals I have brokered..

If you never raise rents on an existing tenant in a rising market, you may end up way under market and not keeping up with increases in insurance, taxes, planning for future capital improvements and other expenses.Small increases when the market is rising are a very good way to keep a good tenant as they won't find anything better when they look around as long as you keep it on the low end of current market.    

facility,property,unit doesn't have to have a pre-existing approval.

How do existing home sales come into play?

Do not figure numbers for future renters at future prices that don't exist. 

I are planning to invest in existing housing between Denver and Boulder; ideally fix and flips in the $180-$250K range.  

The flat roof issue will exist regardless of whether the property is OO or not.

It's not terribly urgent, but necessary sometime soon.Freaking out at the 5% in costs, about $4000 minimum cost to just refinance the existing balance on a property that's making 15%.
