Well, first Brett, HGTV producers manufacture a lot of "catastrophes" into episodes to make the episode dramatic.

But if you're not all about cash flow and if those properties are good producers then biting a bullet to take care of the cap ex issues now for another 10-15 years isn't a bad idea either.Personally I'd lean heavily on what my true ROE is from net cash flows. 

However, mobile homes can be very lucrative in producing positive cash-flowing investment properties without the big price tags.

I own a rental property that has a lot of equity in it but the bank tied a summer home onto it and now will not do a cash out refi because the summer home is personal and is not producing any income, I wanted to refi and have summer home stand alone.   

Will a cell tower with a lease paid to the new buyer raise the value of the property because it is income producing?

They all meet the 1% rule/test Brandon (from BP) teaches that for a SFH make sure each unit produces a cash flow of at least $200, and for MFH $100 per month. 

Tesla has signaled interest in Texas over the past couple of years, but rumor now has it that they are very likely building their newest “Terafactory” in the Austin metro area to produce their new Cybertruck and Model Y.

If you produce leads someone will help you run and harvest them for part of the profit.

That is extremely hard to find, yet this video says anything that doesn't follow the 1% rule isn't even worth it, as it most likely won't produce monthly cashflow.

We're looking at starting small with something like a condo to produce + cash flow and work our way up to multi-family units.
