If you're concerned about costs, maybe a smaller condo may be better for you. The downside of condos is the all of the restrictions via the HOA. I know a contractor who did work on a condo and it took almost a year to finish due to the HOA jumping in and shutting down the project and forcing extra requirements be met due to all the noise that was being made.
Also, some condos will only allow a certain percentage of units to be used for non-owner occupied buyers so you'll want to check with that.
If you're pretty handy, DIY can save thousands, but you must also factor in the amount of time you spend on the doing the project. The time value of money should always be considered. Doesn't do you any good to spend 7 months on a project to save 10k when you could have finished and sold it in 3 months and possibly have done 2 projects by that time.
My first house I found abandoned In a farmers field.
Went to the county clerks, looked up the owner and sent them a letter offering to buy it as is for a small amount down, monthly payments and balloon in two years.
Worked out very nicely for me
