They like the flexibility and predictability of renting, but purchase for investments.Understand property taxes in different markets.

- No one can predict.

A lot of investors are having a tough time with appreciation plays penciling out right now because (1) they feel that prices are elevated (2) their prediction for future appreciation is not as high or as predictable as it has been for them in the past and (3) the cash flow is low.Real estate is local though and there are opportunities at every point in the cycle (#7 above). 

I know how to track/forecast predict end of life on capital items like roofs, driveways, HVAC, appliances, etc.

Time your purchases, no one can predict either way most likely.

If you are looking for a 100% risk-less & predictable place to park your money I'd suggest a CD at your local bank.

Columbus is an incredible market (real estate and quality of life)...everyone loves where they live, but it's really exciting to see the growth and expansion of the city here...I wouldn't hesitate to say (besides the weather in the winter ;) Columbus is one of the top 5 cities in the country...my prediction was the population would double 2-yrs ago and everyone laughed...but the city is on track to make it happen.Is there a particular area of the city you'll be focused on?

I predict the market will turn within the next 2-3 years as soon as the supply and demand picture changes.

Over that time, I have seen the city come alive and grow faster than nearly anyone could have predicted.

I actually predict a influx of rentals of the sell market next year, when the new landlords of the current and past couple years realize the promised cash flow is nowhere near expectations, their property taxes have increased 30-50%, and they actually have to put money in every year.
