Does anyone have any ball park numbers on how to estimate rehabs in dc...

But If I ever really just need a good accurate estimate I will call a realtor familiar with that area and that can do an estimated analysis to give you a good ball park value. 

I've been eye-balling these 2 cities and Madison seems to be terrible for cash flow..  

Then I have the advantage to low ball the offer and negotiate a really good price.

I will be targeting two areas; a fix & flip to pull out the cash when I re-finance or a multi-family home (2 or 4 units) to live in one unit and rent out others.I am considering partnering with a hard money lender on a deal to get the ball rolling...or should I just wait to save money myself?

More experienced flippers can ball park, but for your first few deals you will probably want to walk the deal with a GC to get your quote. 

If the property sits for a while and or higher bidders become unable to perform, they may circle back and ask if you want to re-bid or play ball and you are likely to get a decent deal then. 

This is crazy that they even have the balls to charge that much.

Even then, prospects were low-balling me.

I’m an auctioneer now and I feel this would really be a great business to go alongside that, but I’m struggling to get the ball rolling.
