since you've used 'fiancee' for the correct gender, i'd say you're ready to buy a house.
shouldn't it be 'fiancée' - if we wish to be linguistically true?
Yes, but not everyone is familiar with when to use é and when to use è. At least OP had the extra e.
that was my rationale. the é is a special character that most people probably don't know how to type on a keyboard. (i don't either fwiw)
back on topic tho.. i would add to ketchup's list that if you're on a marriage track or life-partner track then buying a house is probably fine, but if it's just a partner for now type of relationship keep renting. you want your relationship to last as long as the mortgage or at least as long as you plan to live in the house.
in Houston be aware of the flood plain obviously, and at $150k are you looking at townhomes? be very aware of all the potential issues that come with townhome HOAs, shared building space and maintenance. i'm renting a TH now and there was a problem after Harvey with all of the units flooding and some people walking away. there was talk of selling or not selling the whole property and factions of owners on both sides fighting it out. also collective upgrades like going from a 1960s era central tower cooling unit to individual ac units was drama. currently the whole property is on one electric meter with shared payments. some owners are pushing to install individual electric meters, but a faction of heavier users is blocking it due to their use, plus it will cost some ridiculous $$ to rewire the whole place.
on the other hand, Harvey was a freak storm and if you're handy, you can pick up a house with no drywall right now for pretty cheap and build it out your own way.
