As a loan officer I will only give the basics here as not really a great platform for communication in regards to this.
If you are looking at condos a couple things to think about regarding financing: if you are going to go FHA/VA the condo must already be FHA approved or else you are pretty much out of luck. If you are going conventional financing, make sure the bank you are working with does a condo questionnaire early in the process- even in the prequalification stage. This way, you are not out there spending money on inspections, etc. only to find out that the condo would not qualify for sale on the secondary market, and you are out the money. Simple things disqualify such as any current litigation, an owner owning too many units, too high percentage rentals, etc.
Also, in qualifying for a loan, as well as for your own personal expenditures, you will need to factor in the HOA/condo fees in to your total monthly payment along with the principle, interest, mortgage insurance (if any), taxes and home insurance. If all these are still lower than your typical single family residence than it is something to consider- sometimes it ends up being actually more or equal to a SFR of higher value with out the condo association fee. More than anything, talk to your bank/lender first prior to talking to a realtor, etc. as the most work you will be doing is with the bank, or at least it will feel that way in the end. Condo's have become a sort of four letter word in some areas, so make sure whoever you are talking to knows what they are talking about- and takes more than 5 minutes to tell you only what you want to hear.
Good luck with it all.
