I know there are things I need to do to analyze if the deal is a good one, like rental rates, Status of the house/infrastructure, amenities in the area but what else should I be thinking of? 

The BBB accredited status is "revoked" and no action can really be taken other than when I was providing information reference our 1U filing with the SEC so they have the latest information and attempting to assist each input the best I could. 

For example , the rental amount doesn’t depend on number of bathrooms, garage, basement status or property size.

At a minimum they require babysitting (response to a PM company), research, and educated decision making (accredited investor status).

Do you have Real Estate Professional status?

Perhaps they can provide weekly updates here on the status of the development.

Call them and verify employee status/account paychecks drawn on?

Bank of America’s business credit cards seem better, but I’d need to hit their Preferred Rewards status to reduce fees, which might be challenging.Amex: I like Amex’s reputation and services, but their outgoing wire fees are higher, which is a downside given how many wires I send.My ideal solution would be a business account with minimal wire transfer fees (especially outgoing wires) and a solid business credit card option, preferably with no foreign transaction fees.What would you recommend for someone like me who does a lot of outgoing wires and occasional foreign transactions?

Maybe they've been burned by landlords in the past and are being very careful.You can legally reject them based on personality, facial tattoos, body odor, or other factors, but you better make sure you can prove that it wasn't based on any protected class like race, religion, familial status, etc.

Once you have the owners name you can check the status in pacer on the bk.
