@Oren KachelYour title company should have recommendations.

The 5 books that I recommend reading are:1.

I highly recommend 24 hour closing.

As far as electrical I got 3 bids and then priced out the costs for the meters and fuse boxes on EBay at the recommendation of my electrician and saved a bundle.

Any suggestions or recommendations for pros who can help me out in the NYC area?

I recently came across a company recommended by a friend, but my initial contact, whom I connected with via Facebook, is no longer active, raising some concerns.

They should be mutual indemnification clauses.Here is typical language we propose and 90% of the time it is agreed upon, as it is short, sweet to the point and protects both parties: (note I am not an attorney and recommend you always have an attorney review any items in an agreement)Owner hereby agrees to indemnify and defend and hold Manager harmless from, and to defend Manager against, any and all claims, charges, debts, demands and lawsuits initiated against Manager in his capacity as Manager.

I would also recommend attending a couple of in person meetups so you can increase your chances of learning more from others. 

I do not recommend locking a ton of HELOC money into anything for years and years.
