I don't plan on sticking to one method of investing however I do realize that some investors start with Single family and grow into multi-family.

This purchase will be up ~1m over purchase price after this rehab is done (3 sources: 1) purchase below value (or value add from addressing the rent issues - depends on your perspective) 2) value add from 4 class b+ unit rehabs 3) natural appreciation).  

Be interesting to see the inner workings of the deal and how it was underwritten.The big question in life, not to be or not to be, not nature vs nurture, no, what is the difference between a HML and a PML? 

The math is obvious but there's a natural tendency to go for properties you can obtain at a lower basis.

Even though I had a full size W/D on site, I still used this method.....

Having them deposit the funds in your account each month is the only other viable method IMO.

The market can be tricky with its block-by-block nature, but it's been a great fit for all-cash purchases like yours.I also have a team on the ground in Detroit that helps manage everything from finding deals to overseeing rehabs, which is crucial for out-of-state investors.

Any recommendations on local networks or specific methods that have worked for you?

That feature is bundled in a Resident Benefits Package I have as an addon through Second Nature. 

Eric,Without going into too much detail on each line item, at first I use my back of the napkin method with a 40-50% expense ratio.
