This means you need to evaluate your metro area's neighborhoods.

I go buy each day after work and evaluate progress, discussing with contractors next step and any issues.

This being the case I have put off a mortgage and was intent on saving over the course of 7 years towards the ownership of a home, at which time I would re-evaluate my position.

What should I look out for to evaluate this deal? 

A tenant reported a tree branch fell down in a storm and would like someone to come evaluate the tree so they don’t have to worry about a branch falling on he or his wife. 

I'm currently evaluating new target markets for investing in multi-family properties.

Getting the contractor in to evaluate what you want done is certainly the next step to help you determine the actual costs. 

Now cash flow is important but it's not the only metric to use in evaluating your objectives.For instance, if I don't make a dime in cash flow on all of my properties, I still pay down over $100k a year in debt just by the way the mortgages are amortized. 

I am just starting out and have been in and out of several properties and am at the point where I am looking for contractor referrals to attend walk thrus with me to help me evaluate rehab costs for SFR properties.

I see value-added services by offering financial evaluations and creating personalized spreadsheets that helps the buyer stay on path to ownership (whether it be credit correction, or debt reduction - would be personalized), creating solid contracts (my partner is in law) that protects everyone and preys on no-one.
