Folks sign D-I-Y contracts all the time without involving lawyers, but R/E transfers are special kettle of fish for which you may want professional help. That said, a D-I-Y contract is what I sent to HGVC to get them to sign a ROFR waiver. You can D-I-Y, if you are fairly proficient at adapting forms or samples (which you can find online) and then, following directions. OTOH, if you're the kind'a person who can't be bothered with little details, then maybe this should be left to the pros.
When it comes time to executing the sales contract, you may want assistance from a closing service like LT Transfers. There's plenty of positive posts about them which you can find on this forum.
