People who sell to developers have properties in disrepair that they cannot afford to maintain.

Set up some bunks and a coffee maker, stock the fridge with some muffins and eggs and offer up as a fishing camp? 

I don't understand enough about it to know if them stocking up on single-family and small multi-family properties in the Denver area, at the current prices, is a good initial play that will hold up.

There are also additional costs of operating and maintaining an LLC, like separate bank accounts, annual report filings, tax filings, etc.2.

Open communication is key in maintaining a positive landlord-tenant relationship, and being transparent about potential changes can help avoid misunderstandings.

Keep in mind this doesn't account for rehab, repairs, and reserves necessary to maintain rentals.

Optimize your finances by reducing debt, boosting credit, and maintaining strong cash reserves.

One option is ServiceLink, which provides auction services and maintains listings for properties that have been foreclosed and are now available as REO properties.

I just maintained it, managed it myself and then sold it to the tenant.

To maintain my rates, I had to offer more than the competition, which also increased my costs.
