It sounds like the standard spam in the mail.

I suppose the advice that I am looking for is: am I going to be taking on more than I can chew trying to tackle the rehab myself?

I doubt spamming people with the merits of BP is going to make you the kind of connections you are looking for.

A lot of list sellers sell and resell and by the time you get it the data is not only out of date but they have been pestered so much they do not want to know if they are not simply spam data copied off the net somewhere. 

I recently contacted a 4-unit owner about his intetest in selling his rental property. this is an off market deal. below is what i got in response. any advice on what steps/actions on how to tackle this?

The sweet spot would be to partner up with the owner of a construction company (or someone who knows the rehab business really well) and tackle it together.

I justified this because I could tackle this down payment on my own (no investors) and I wasn't relying on the cash-flow to get into the deal.

You are spamming the forums. 

And in your experience if I decided to tackle this head on as you say what does the average work week look like hours wise?

It has been 15 months now and I have certainly learned a lot.The answer really comes down to what you plan on tackling yourself vs what you plan on hiring out.Rent Collection can be a pain if you are waiting on a check to be mailed to you or if you go door to door collecting BUT there are several online options available now that make it much easier.Accounting is not too bad, just make sure you are doing it regularly...I spend about 30 mins-1 hour per week and it is very doable...just make the time for it and stay consistent.Maintenance is by far the most difficult aspect...if you are not a handy man then you will need to hire out the repair.
