To avoid issues with the title insurance and title chain you would want to use a Warranty Deed. 

(I assume that means that the warranty deed will be in both names?).  

So far, I am looking at services offered by "investor oriented" paralegals ($90 to $150); however, I don't see any kind of job warranty and that make me nervous.Should I better go for the services of a Tittle insurance company that may also issue an insurance commitment ($300+)?

Hello all, I have a quick question about the Cap Ex and having a home warranty; are you not preparing for some of the same things by having a home warranty as you would be by setting aside said amount for Capex? 

Get a warranty deed as well.

Some clear the title and offer a warranty deed, and others only offer an AS-IS sale with a quit claim deed.

For a few dollars more a bundle, you can get a dimensional laminate shingle which is basically two shingles laminated together that gives it a dimensional look and a 50 year shingle warranty.

After a VERY close parcel look up it was determined they were actually on two different lots, although if you looked at them you would swear they were on the same lot.In your case if they are on the same parcel.....simply figure out which duplex is higher value, and have an agreement with the seller that you will buy the higher value duplex for $200K as long as they sign a warranty deed that also gives you ownership of the other duplex as well.If they are NOT on the same parcel after all then you may need to get 2 separate loans...... 

Why not offer the buyer a home warranty?

What are thoughts on building in a home warranty on your purchase to help with unforeseen issues into the first year?
