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%.  

Next issue:  The existing lease is very thorough but has contact info from the previous owner.Should I:1) Draw up another lease? 

As a result, effective termination would occur on 30 May 2016 - which the existing landlord could do at this point without cause.

I want to take over the deed, pay the existing mortgage up to date, leave the existing mortgage in place, place the deed in a land trust, rehab the property then pay off the mortgage once I sell the house off.

Hello, I'm new to real estate investing and wanted to get started using the "subject to existing mortgage" strategy to buy and hold (landlording) to build wealth.

We were very very careful to make sure this wouldn't happen because of all the interest in the property and it's common for people to pull these shenanigans to get a property under contract and accepted for a ridiculous price and then later back out and reduce the offer for the "appraised value" so we wrote a special clause into our counter proposal.On top of all this the roofer that I had hired took my $1k and ran off with the material money and also hired and scammed another roofing company that tore off the existing roof.
