If you pay all your bills on time and keep your utilized revolving credit low, this will not be your problem.

We do the 1-year guarantee because turning a rental building into to a revolving door of renters to collect lease up fees and eviction fees is a death march that ends in foreclosure.

It worked in 2 instances where neighbor cam eto'o me and I bought.

I’ve also been advised to get a revolving business line of credit to fund the 20% down that most hard money lenders are requiring nowadays (especially for new REI) What’re your thoughts on lines of credit?

Some of this is for the fenced yards, green grass, fresh air, but a lot of it also revolves around the school systems. 

If a NNN property had more robust CAM expenses that a landlord had to manage and bill back to the tenant and multiple tenants, then a property management fee would be more applicable.

You would do this by running out the remaining lease obligation (rent, CAM, reimbursed expenses, etc), and discount it back at a specified discount rate.

It didn't really make intuitive sense that we as tenants would be responsible for paying the taxes, insurance and CAM of the property owner but we figured that if it were really only a few dollars a sqft we could live with it.But our experience has been that triple net is far more than a few dollars a sqft.

There are now Ring Cams all over the place, and Wyze cams in my apartment.

Lol lol For buy and hold see the business model paper off my profile 1st paragraph called bulletproof rental portfolio.A deal calculator is useless if you don't have a business strategy.After 40 some by and holds not even a calculator is needed it's mental math and yes revolves around the approximate 1% rule or whatever represents a good deal in your area.Like I said too much emphasis is made on complicated spreadsheets that account for every expense under the world and that ultimately kill good deals.
