If you are interested in doing a search, search "property address search in NYC" and you can find Department of Finance Web App to find out Market Value. 

How do you go about finding those (any good web site focussed on new construction?)

They put it on the web!  

If you are looking for wholesalers, just do a web search “sell my house fast Plano” and you will get about 20.

https://www.waynecountylandrecords.com/recorder/web/ so go here, create an account and search by the address of the property you are interested in.

I find info on the web a bit murky about this.

Finally, it provides sample letters you can customize and use.NOLO web site is a great resource for state law.

Current have a web site but the company apparently has gone out of business. 

Its not easy to be that brave, you've done it, will learn from it and will come out on top, keep the positive attitude and always be on the lookout for solutions...this is just the beginning of what may well be a very bright investing future. 

I know i want to wholesale deals first so that i can get a different feel for it all cause the rehabing part i know i can do that hands down i mean remember ive been doing that for years right but should i get my llc ,web site, cread packets , business cards, phone number,ex.... first or just market to find homes for sale with out any type of credability or protection from the llc ?
