I would concentrate on Absentee Owners, Tired Landlords, etc.Good Investing...

I explained that my goal was to acquire 1 property a year (through loans) for the next 5 years while I still had a W-2 to help prepare for retirement.After he put together our fin plan, he advised me that I should hold off on these properties and instead concentrate on putting more money into my 401K (currently only putting 5%, no employer match) and to pay down the existing loans for two of my other properties.

I’m leaning toward multi-family residential properties, as I like the idea of having my investments somewhat more concentrated to take advantage of synergies.

Concentrate on being the "contractor" partner and having rights to workmen's liens which can force sales.

Having kids around will never be a positive...you can avoid it being a negative, but at least for me, with my kids around (3, 5 and 7) I wouldn't be able to concentrate on the deal and they would definitely be a distraction to the seller. 

I have been told to concentrate on the buyers side because we have inventory.  

As part of the hunt for the first deal I'm concentrating on looking for homes with terrible yards.

I have been concentrating on cities in the Midwest.

I would concentrate on the numbers of the deal.  

Should I diversify my list more to different prospects or should I just try concentrating on one group for now with the first 4 rounds?
