New townhouse

We have bought a new townhouse our friends have seen it, did a walk through and our lawyer has done his do diligence. Have a few questions that expats can answer i think.

1: I know lawyer will handle transfer from builder to us but if you have any other info we should look out for let me know. Who do we call or email to setup i assume water, hydro, etc. any info apricated.

2: How is it driving in Dominican i have read only need our Canadian drivers license , Insurance? roads, etc. I am thinking rent a car for few months we are there, we have designated parking spot but i don't think leaving a car there over summer very hot no one driving is a good idea?

3: We are using a company that buys in united states, ships, does customs, delivers and setup very reasonable prices compared to buying there and even here then shipping. We are sending barrels of small stuff from here via ShipDR which is great. Question i have read buy fridge, stove, air conditioner units from there. Is there anything that is better to buy there then ship? large items?

4: Is food (buying from supermarket) reasonable i have read can live on $100 US a week is this true?

Any help apricated and looking to enjoying a cold beer the next January while in Toronto it -25 and snow
