In Ann Arbor, if a dwelling is cited three times during the winter by the Housing Inspection Department because the heating system will not maintain the required temperature without portable heaters, corrective action (e.g. storm windows, insulation, additional heating capability) may be required.

. -- but, on the other hand, there is also typically less volatility in your income stream because leases tend to be long-term and can be structured to insulate you from most operating expenses.

I highly recommend the book "FLIP" as it identifies those tasks for you and also provides an excellent workflow chart to keep the process as efficient as possible.

This spring we gutted the downstairs unit - as expected there was no insulation in the walls (typical for 120 yr old ballon framed buildings}.

If you haven't yet, I would recommend checking out the BP podcasts, they are an excellent resource in addition to the forums and blogs.

Both excellent reads.Read everything you can.Paul

@Mark F. excellent question...I've learned a lot about property analysis from podcasts, books etc., but there are certain aspects of property analysis that I've had to learn mostly from experience.I often think of property analysis in two ways: First is "the paper assessment" (which includes the P/L spreadsheets, the appraisal, SQ footage, data on the local market, and all other info that can be easily conveyed on paper--or at least on a computer). 

Easy, and excellent customer service.

We did  gut renovation two years ago, currently have a leak in basement from side of house and the house shakes on windy days, it’s a 3 family house detached, 20x60. had many issues come up, more recently had walls opened for spray insulation, and noticed the corner post is rotten from first to second floor.
