I bought a house last year using my VA loan. the house was in great shape, and we had no issues. the only thing we had to do to the house, the VA required, was a hand railing be put on some outside steps. I helped the home owner install it.
IIRC the longest delay we had was the appraisal, which took about three weeks to get ordered, done, and reported to us. we started buying the house around the middle of january, and moved in the first of march.
you wont be buying a dumpy fixer upper / a house with a lot of issues with a VA loan however. they would require you to rebuild the house before you would get the loan approved.
VA loans basically treat the home buyer like a child who has no life experience.
yeah, you need to get a new roof before we sign off, oh, that plumbing is not good enough, fix that first, etc. from what I understand, its the result of people buying houses with big problems that they ignored, then they later made a stink about the " VA" selling them a shitty house / not protecting them from a shitty roof / foundation, etc. that they cant afford to fix. so, the va wont sign off on a house unless its in perfect condition, and should go 20 years before it needs anything major.
