Plain and simple, knows his stuff.

Sometimes even 7 or 8% lenders are had to find for 3 or 5 years much less for 15 or 30 years. exactlybut im sure its possible because people are doing it Possible yes, but there are a lot of complexities and moving pieces - this is generally the lending business model, not a simple "arbitrage" glitch or easy scheme..

Keep it simple is great advice.

I've been in this situation a billion times- honestly, the answer is very simple.

In my case it was not as simple as wake up and do it.  

At its core property management is simple though.

I manage the property and the tenants, pay the owner of the property a rent that meets their mortgage plus a little profit, charge fair market rent from the tenants I sublet to, and exercise an option to buy the property after a predefined term and at a predefined price.This way tired landlords don't have to manage their property anymore, and I start investing with little to no money.

I am the only real estate investor with my bookkeeper and at first she thought this was a little overboard but once she started setting rules in Quickbooks to simplify her work she quickly realized how simple this method makes things.

I don’t have an STR myself but have helped a friend set up and manage a couple last year and it’s not as simple as it used to be. 

Can I still do simple 4 box calculation?
