Single family units are more costly when you have a vacancy.  

As more and more people convert these to single family homes, the two flat becomes more and more rare in this neighborhood and more desirable.

ERGO you are in foreclosure in the first place.GFC meltdown saw values drop 20 to over 60% in certain markets  .. your 70% LTV loan was underwater right out of the gate.So to answer your questions.In General... you have a foreclsoureyour value is 10% less than it was when you made the loan.. reason flipper butchered the job ... and again depending on state it could take 1 to 3 years to actually foreclose and of course your not getting any payments.. so your interest is wiped out. your cost of doing the foreclosure again state specific.. and I have never met a defaulted borrower that paid the property tax's  ( and again state specific how bad this will be).. you have selling costs usually 8% and you normally have to spend money getting the home marketable I have never met a defaulted borrower who left a home in perfect shape.So you add 10% market devaluation  8% for sales costs.. 3% for foreclosure costs.. 2% for back taxforce placed insurance and utls.. and depending on the condition of the home 5 to 10% for rehab .. you can see how this eats into your 30%  .. then take states Like were i live and properly filed mechanics liens are super liens they jump ahead of your mortgage.. this can be thousands up to 100 thousands if your flipper totally screwed the subs. 

I am super excited to meeting other investors or possible joint ventures partner. 

I can't remember exactly, best to get a HVAC company in but its not super cheap

Then I believe I could move into some buy & hold single family units through foreclosures or tax liens again.  

Good morning BP.I am trying to find out if there is a way to get select data out of the MLS system and into a data table such as Microsoft Excel.For instance, if I specify all Single Family units in zip code 77042 between $100,000 and $150,000 I want to get all listing in the MLS meeting that criteria into a spreadsheet that I created.I am trying to do this so that I am not tethered to the MLS and I will be able to review the listings even when not online.Thanks.

Hi @Elizabeth Lester-MedadoWe are based out of Clinton Township and have a large number of fully turnkey single family rentals available in the surrounding areas.

Long term goal is to have enough rental properties, single and multi family, to have enough passive income to be my own boss and financially free!

In addition to the podcast, blogs, and forums, I found the BP books to be super helpful and easy to digest: http://biggerpockets.com/books and there's also a free intro video course that has a lot of the same material as the Book on Rental Property Investing: https://www.biggerpockets.com/courses/a-beginners-introduction-to-real-estate-investing
