If you want to PM me the address and info I can give you more specific opinions on the property and what this turnkey company is telling you about rents.

His insurance company has denied his claim.

Many states now require new funds and do not do pass through.. its the reason we all are in business us bridge lenders.. also I know in Oregon the title companies demand a full profit disclosure to the seller.. they don't want to be sued for participating in a secret or unconscionable profit act.

I did enquiry with some insurance company but lot of not providing insurance to rental house. 

I was wondering if anyone knew of a real estate brokerage company that is investor friendly in the Phx area?

We just did a portfolio review with our insurance company this afternoon.

Whoever told you that was wrong...a simple google search would have shown you that. 

As for the rodents, call a company and have them come out and deal with it...take photos before and after so if the tenant does something (ie puts out more rice), you can show that the tenant is deliberately doing things to attract rodents.

I am hoping to get a few tips on first, how do you get the conversation started with leasing companies or agents?   

I'm planning to buy one of their lots of 500 m2 but not sure if it's safe to buy with this company as there is no information or reviews in the web about Viventum or Sustenthabit which is the company behind this development.I gave the reservation fee but before signing the contract and give the down payment I'd like some advice.Any advice would be appreciated.
