If you give them a chance to pay on their promise date and they were being truthful, you will have avoided a lot of time and cost associated with filing the eviction and then cleaning/fixing up the unit, marketing, and not to mention vacancy.

Your could rent it out for a couple of years to avoid any red flags with the tax man.

The buyer also gets the benefit of avoiding other underwriting standards and the associated processing delay that comes with.

I recommend your lease include a minimum 3% annual increase so the tenant is always expecting it and you avoid falling too far behind.Give them 3% or $25 or something to that affect and they can either accept it or move out.

They're either marketers calling themselves turnkey (ie they don't own any properties, they get a referral fee from other TK companies around the country for sending buyers) or they're some sort of Morris Invest house of cards (search the forums for Morris to see what to avoid).Go ahead and shell out the cash to get your own inspection and appraisal, especially on your first deal with a provider.

In case they link account etc.. looking to avoid potential for issues?

The duplex isn't in the best part of town and the vacant unit needs some work before it is ready to rent (smokers), so I'd rather avoid living there if possible. 

It can make great returns and avoid tenants, toilets, and property tax bills. 

@Michael Ealy When you see high foreclosure filings do you tend to pounce for the deals or to avoid because of the neighborhood?

By taking steps to minimize your exposure to risk, you can avoid large, costly errors that will cause you the biggest headaches.
