I'm combing through online County records in an area of Minneapolis that I'm planning to market to, and have come across several properties with no information identified for a previous sale.  

Go over the sale list with a fine tooth comb.

Comb your markets MLS daily.

before splitting hairs on depreciation and tax benefits decide what your skills and your "why".and, unlike me, weigh downside risk as likely. things go wrong all the time. any wisdom I have now comes from big mistakes.That said, a group of mobile home parks in the same area makes sense.

A fin comb is like $7.

Hair drier, iron or steamer,Coffee maker,Some oil and herbs in the kitchen "Good quality" linens can grab you a few good review mentions

Hair salons, nail salons, yoga studios, Dojos.

We are early in the process as we have not had an opportunity to comb through the financials, yet. 

The reason why I am pulling my hair out is because a single family resident are worth more than a duplex in South Pasadena and it seems that if I am going to gut out the property its better if I went that route. 

I've listened to a lot of gray-haired investors and they say the same thing.
