They are relocating and we are unfamiliar with the market.

WI is a big market. 

My role involves raising capital and collaborating with investors interested in leveraging my business to facilitate their acquisitions.

At the end of the day, having adequate capital to purchase deals is a crucial part of this industry.

Any advice on most efficient and costly ways to obtain marketing lists in S.

(I'm not really interested in the Orlando/Disney market.)

If there is any way you can avoid marketing to section 8 you will be far better off especially in regards to the quality of tenant you will get. 

I'm thinking about ramping up my marketing and having agents send me deals with their criteria.

@Dave Rav - I agree with the others that there is no really good way to estimate insurance costs, but I've found some consistency within a particular market/zip code if the rebuild costs and deductibles are the same.

As an investor, your primary goal is probably to buy at the lowest price (you make your money when you buy at below market value), fix it up, and either hold or sell/flip.The seller might realize they "don't know what they don't know"....in general, investors sometimes come across as "transactional" (they ran the numbers, and just want a yes or no from the seller).
