If you're not in a rush, and you can wait, then you'd be able to focus most of your effort on bootstrapping your new business.In an effort to help persuade your wife to toughing it out longer, try explaining that if yall stick to option three, you could potentially get a bigger/better new construction house later *and best part of all* another horizontal income stream (i.e. rental income).

If you don't split the lot, then you're essentially making a horizontal condominium complex. 

Or as Sparefoot has done, they go Horizontal and provide Insurance or Operating software within the same industry.  

@Connor NellansWhat if one went around to homeowners and bought the opportunity to add an ADU to their backyard for a monthly fee then found a tenant who would bring in the tiny home and lease the backyard for a second higher fee and pocketed the difference One could create a horizontal mobile home park.

Additionally, I want to expand the horizontal space of the driveway that it takes up slightly more of the front yard but would fit 2 cars side by side. 

You may have to fuss with it a little to get it right.Planks can sometimes be a little warped horizontally, but so can hardwood.  

In our experience the exception to this is many old - Second Empire, Victorian, Edwardian, ballon-framed houses had horizontal cross-members in the wall cavity spaces (aside from the plate at the ceiling or floor).

My experience has been that vertical cracks are a sign of stress whereas horizontal cracks are a sign of structural problems.

As far as the plumbing I am just taking out Horizontal metal pipe and replacing it with Pex.
