There are lenders who even if you haven't filed your taxes can use the income to offset your PITI, which should barely raise your DTI, especially in the type of example that you mentioned. 

I''ve only heard of ones existing who work on large constructions projects, not small single family home investment properties.City inspectors will inspect as part of the permit process.

So, I have money in vacation communities, apartment complex's, mobile home parks and even a manufacturing plant.

Even the tenant can sue you if they injure themselves.  

My wife and I own a single-family home in a top school district.

Purchase price: $200,000 Cash invested: $30,000 Single Family Residence holding on to.

So we reached out to 80 builders who build at least 1 single family home.

Instead of moving into another single-family home, consider house hacking a duplex or triplex, this allows you to use low down payment loans (FHA, conventional) and offset your mortgage with rental income, accelerating your path to financial freedom.

I am single with no kids.

It's because I care that I'm even taking the time to reply back to you.
