Excellent idea, Charles.

In my area I've found that many (not all) MF properties that are "mixed in" SFH neighborhoods are nicer (and pricier) than those clumped in a pocket of MFs.My advice (as a newb) is that if the numbers work it could be an excellent opportunity, but make sure the cash flow works with both sides rented out (non-owner occupied) and with property management fees.  

This provides an excellent chance to command higher rents, especially if the property can use some rehab to become a higher quality product with new higher quality tenants willing to pay more.

If it's in excellent condition, you'll need almost no maintenance.There are deals in every market.

Excellent.

Since you are young, your earning potential is likely to increase so depending on the costs involved and finances, and those you have to help support and educate you on the process of home ownership and landlording, it could be an excellent opportunity.

I am therefore thinking about a service (Website or Excel spreadsheet) which would help investors find where the best yields in the country are based on extensive research.What do you think?

I have a 'newbie' question....I currently do not have a 'primary' residence, as 'my' house that I built and raised my children in 15yrs ago I converted to a duplex about 4 years ago and have been living in the building I rent to run my business as that is where I spend most of my time and it just made sense at the time to let my house pay for itself.I have recently decided to go into real estate investing and have found a wonderful triplex that I know will be an excellent cash flow investment (yes Ive run the numbers every which way and it all makes sense, have even had other investors run the numbers to make sure I didn't miss anything) .... so the deal I believe, is really strong.My problem,... since I have converted the house I own into a NON owner occupied duplex, I can not get a HELOC to fund downpayment on triplex.  

@Jeff Arndt Interesting to see how you are tracking your goals - this looks like MS Excel?

An exterior drain tile system also has benefits, in that you now have access to the exterior basement wall, which you can then seal and install the proper membrane and fill with gravel for excellent drainage but is mu h more expensive as it requires more work and many times harder to access.The price seems a little high but it might just be your area compared to mine.
