I currently own 15 rentals with no debt and plan to hold paper.  

I have never done a land trustWe have a living revocable trust that we set upHonestly I should have done it 15 years ago but did it like 6 years ago.I do not see the need for a land trust unless you are a politician, actor or athlete (someone who is famous).I have done business with multiple billionaires (not bragging but trying to make my point) including several that owned professional sports teams - and even they did not use land trusts…

Do they usually do a monthly flat rate (this would include the winter when its not needed)?

You can read all the details for yourself here:Why Viceroy Research is Short on Arbor Realty TrustBelow are some snippets that are included to link this report to individuals and entities that have promoted here or have had investors discuss the investment here so when people search for them they can find this data."

What is included in the rent? 

Dealing with nightmare sellers, including a dog left unattended for days, a break-in, and hidden foundation issues sounds like a real challenge.

You can go up to 75% cash out and use a DSCR which will off several terms including I/O Interest only which helps keep the payment low while you take out the cash and pay it down or off.

Otherwise, I spend a few hours on bookkeeping each week, but that includes all my properties and business entities. 

The purchase price is listed at $285K and that includes ownership of the land, laundromat, and shop. 

You are both earning so that doesn't change.Is one carrying a bunch of other debt?
