What is a competitive interest rate to offer/ what other levers can I pull to make the offer more beneficial to both parties?

Where I can find those tax amounts from an independent source (read: not involved in the RE transaction) in order to analyze the deal?

(no third party)Sorry about the confusion.

only you would be able to decide that , everyone has different levels of involvement and different means of "justifying"...

Why not involve them from the beginning?

Hi Ricardo Welcome to  Connecticut MarketBidgeport is a good market depending the area like any market you can be in a nice are and 2 more  blocks down you'll be in a war zone but the best part is that bridgeport has the most affordable market compare with the others cities closed to NYC like norwalk not even talk about Stamford here the taxes are little high but  the income compensate that be careful with Real Estate Agent that says they are Investor Friendly and they just want you to buy at high price so they get a good commission but over all bridgeport is a big city trying to get betterbest area is black rock but is expensive, Hallow are is good for cash flow but a lot of the area is hot zone, east side war zone but could be some ok section, north end on the border of Trumbull nice are, east end like Stafford ave and Connecticut ave this are in this days is war zone. all of this areas and what I said about them are my point of view so you can see what others investor says about it wish you the best on your investment and see you on the top :-)

I have no plans on getting involved on the sales side. 

I have some negotiation tactics under my belt but I am hoping to learn about some tactics involving talking to land owners about selling their land or even thinking about selling their land.  

Since I am an out of state investor do you know if they will handle all of the stuff involved?

Seems to me that there are issues with the car that involve some thought since one of the units is on top of the garage.2) anything else to consider?
