As a patriot and a believer that our government is by our consent, I'm a bit sick to my stomach.

It says tenant cannot "unreasonably withhold consent" to show the dwelling to prospective tenants.

Yes, agents do it all the time, often with their CPA's consent and even recommendation, but the legitimacy of such approach is debatable.

I wouldn't text/e-mail until AFTER an owner has contacted you AND the owner has consented to texts/e-mails.

If your family is funding and you are doing the work, how you allocate your profits and losses, who is responsible for what (who can sign contracts to bind the company, who can sell the property without consent of others, who can sign leases, who can engage professionals, who is responsible for tax matters, who gets to decide when an offer comes in if you accept it, etc.), where the money goes when you sell or have income, i.e. do you distribute to the members (or in trust for the children) and in what percentages, do you invest it all in the next property.

Personally, I would keep them on a month to month until you know their payment record and if their will be any problem issues with tenancy (willful violation of terms or they make unreasonable demands, etc) M2Ms advantage to owners is you can raise the rent and change other terms in the lease after giving proper notice without getting tenant's consent.

An attorney can act as a broker and an attorney in the same transaction provided:1.) attorney can protect his client's legal interests even if attorney loses the commission should the transaction fail to close, and2.) attorney discloses the conflict of interest to the client, and3.) the client consents to the attorney acting as broker and attorney  In the original scenario, advising the seller not to sell at 1/5 market value, and helping him get a better deal is certainly not an ethical violation.
