If you hire someone typically they are the ones providing this information, but if someone is paying you, then yes they need this information for tax purposes.BTW - I would say your SS# has been hacked so many times and is on the black market already this is why we monitor ours through other parties or just lock it down at experian and other agencies if you are concerned about it.Yes, I have concerns about ss number safety.

I was wondering if there were any builders who have any good strategies on where to buy land when you're looking for spec homes.

Do you get interest on that money that is sitting there in your home? 

If so, they can sell within 2 years and not pay capital gains taxes on the sell of the home.They could take that money and buy multiple rental homes in other areas if they wanted, or use the money to downsize in to a different home while still having money left over.

Does anyone know of any lenders that will give what were looking for even if the title of the home is in an LLC? 

You can invest in single-family homes, multifamily properties, land, commercial buildings, and even tax liens, creating opportunities tailored to your investing goals.

Not an easy thing, but saving 20% or more on the cost of a new home seems well worth the time and effort if you ask me.

I would also weigh if you plan on staying in the home you are in now for a long time or move in the next 5 years.

Quote from @Geoff McFarlane: We bought our current home in 2011 for $97k.

I just bought it in the fall and am trying to complete a bunch of modifications during off-season (e.g. metal roof, certain safety features, treating the deck, possibly updating the fire pit area, etc).
