I would suggest using "Angies List" if you do not have any good contractors in mind.

Another company stopped by today suggested that they could fix this problem by mudjacking the floor with polyurethane - first time we heard of this.

I would suggest you set up a website also with a nice clean simple landing page to generate leads.Then you can direct your Facebook Ads or Google Adwords campaigns there and it also ads credibility.Twitter and Instagram both have paid marketing tools as well that you can utilize to build an online presence.

How would anyone suggest going about this situation?

I am also open to any book suggestions people might have on any of the above topics.

I looked at some of the features，it really tells something more than agent can advise，if I plan to buy, but not sure when to hire an agent ，what would you suggest？

Like a few folks here suggested, you should be able to buy multifamily with a loan.

Please help any help with answering the suggested answers so I know where I went wrong in part 1 and any additional clauses that need to be included in part 2.I am aware BiggerPockets does contain contracts specific to each state but how much in detail are they i.e do they cover everything I've mentioned and perhaps even more things I haven't thought about yet?

Any other suggestions are welcome and greatly appreciated.

Any suggestions would be appreciated.
