i have been in the research/analysis phase for a time now and i am wanting to finally start moving towarfd taking some real action!

Even if you have that final number,  without seeing the actuals for each operating expense category you do not have a useful number. 

What happens if you don't follow up to do a final inspection?

I have been interested in RE investing for quite some time now and finally think it's time to put some action to my passion.  

Lender Interest and Fees: If you’re using a hard money lender to finance your rehab project, make sure you calculate all of the loan fees, also called points, any junk fees, and finally all of the possible interest you may pay.

I'm replacing it because the copper is very beat up from hail and weather and also has leaks from old nail holes.

Finally go and knock on their door, but mention that you sent a letter and didnt hear back and...blah blah blah, but its important to say with a big smile, "i mailed you a letter (or postcard) and i was just following up and seeing what you think....." or whatever, because that establishes the rapport that your looking for. a warm greeting instead of a cold greeting (ie cold call)Then ask them about it and see what the heck is going on.
