If you are new, you may be held to their standard loans i.e. 15 year term 5 year apr with a seasoning period, but if you are more of a seasoned investor and show a history, they may be more likely to be lenient with their terms. 

With the standard 3x income requirement, you'd need someone with a 100k income. 

So you might have to file a quiet title action to gain title to the property.   

Here are a few from the last year of so with "all-in" prices:Rent $1200   All In Price of $30K    Rent $725      All in 22k     Since I now have owned this property 3 times, it may not meet your 12 month standard$725 Rent  including storage rent  All in $15KRent $625    All in $32K   Oops only a 2% deal....Oh I forgot there is another house on the lot that rents for $475. 

Did you make tenants upset because something was not to standard or meeting code? 

Hi, see http://www.usa-nra-tax.com/setup.html which addresses this point, you can use a) if your country (see http://www.investor-realestate-accounts.com/wiki/InformationForForeignInvestor) has a tax treaty,  b) if sending W7 with filing, h) if asking for ITIN to obtain mortgage.Caveats apply so let us know what you find.

The seller hopes the buyer (gets pregnant) on the deal with tens of thousands of dollars spent or more and also if they have a 1031 exchange they can now be stuck with the choice or face a big tax penalty.If a seller does not have a full file ready to go the minute they go under contract then either the seller, the listing broker, or both are incompetent or they are trying to hide something  and commit unfair dealings by pulling one over on a buyer.

The existing lease was made by us prior to the new standard lease which has to be used now.Can i add the person to the old lease?

They paid the couple 50k and pocketed 10k....much higher than even the standard 10% commission that lots command (but buyers actually fixed up the trailer and now live there so 6% is usual).  

It will depend on what are your standards and goals..
