@Wellsfry It have another solution, it's to come whit a business visa, open a business whit the help of attorney, then your company will buy the land and house, so no problem at all, no risk to see, one day, your gf and his family put your stuff outside and ask you to leave, another thing, be careful whit the deed of usufruct, if you put the name of your gf on it, it's mean you cannot sell the property, until she agree to leave.
