@Michael Dunn Based on what you're saying, I think the most important item to research is how much of the areas with the lower priced properties are majority rental areas.

You want the net income after all expenses like, maintenance, utilities, taxes, insurance, property management (if needed), if the property is vacant figure that in, and Cap Expenditures (any big ticket items that might need fixing or replacing once you own), things like the A/C unit, water heater etc.

Now when we look at the surface items (flooring, kitchens, paint, lawn care, etc that is pretty easy to replace but that tenants habitually destroy) vs the items that really matter and can suck up a lot of funds (electrical, bathroom, landscaping, etc.).  

Your not really going to double your closing costs....some items yes, but many are bases on price, including PMI which should be the same.

There are some other items but those are the big ones that I mentioned.

Refrigerators are typically considered "non realty"or "non-real-property" items since they are not attached to the house. 

They did fix the issue, but the item should have been installed correctly the first time.  

Period.I would buy a condo and keep your personal items in a locked closet (or even a locked bedroom).

A few weeks later they called the board of health on me.I review the items from board of health, and they are very ridiculous.Example, stain on the ceiling (need repair), the toilet seat is old and not smooth (need repair), tenant has no access to the basement, I don't post my contact information in the building ... etc.What is your opinion on this matter if you have encountered it in the past?

They would rather be working on a job that is paying them than to spend 20 hours doing your 4 line itemized rehab budgets on potential homes.
