My money is tied up in bills.

@Lynn Burson   Yes I have owned hanger and rented hangers and tie downs..I would consider developing and owning hangers as one of the better rental investments one could make.. the issue is finding the dirt.. as many times the dirt is city or county or state owned. 

Many are tied to contracts of a few years etc.     

It takes shoe leather and people skills, so if you're lazy don't do it.

I'd say for most, it would be accounting, timing on collections or accounts receivables that tie to notices of rents due.

Called predatory dealing.No, this is no longer the wild west where you get what you can get some fool to agree to, might do that in a shoe store, but not in real estate.Obviously you've never been to court over a real estate transaction where some owner cried foul of misleading valuations.

Tieing up a house you have no intent to buy, so you have time to sell it for more than asking price, and then dumping the house back on the OG owner if you fail IS NOT wholesaling. 

But, an IRA or 401k of the Wall Street variety (common model) is equally tied up as far as your access, and even more restricted because of the limitation on publicly traded investments only.

We decieded that we needed to give the future tenants a backyard so we had to pay an excavator to dig out the yard and build a railroad ties retaining wall and pull off the 2 decks and replace them with cement patios and put a fence there to give each tenant a private patio area and that cost at least an extra $4,500?.  

I learned my money will be tied up for up to 6 months.
