Fun fact: I recently purchased a town house in Tulum Mexico, renovated it (even though it was brand new) and filled it with custom furniture.

Thanks for being a longtime customer (we have many, since we've been doing online rent payment since 2000!). 

I think we would feel more comfortable purchasing a SFH, but are definitely open to small multi-family if it would generate more cash flow for us.

@Hilary GravesA quick google search pretty much consistently shows that NOI starts with Gross Operating Income that includes all revenues generated from the operation of the property i.e. rents, pet fees, vending machines, covered parking privileges, laundry revenues, etc.You mention standards :-) which may be a keyword here.

My goal is to start building passive income and hope to retire sooner and long term goal to develop generational wealth.

I am generating passive income so I can control my time.

What is the typical target customer for that model?

since this is a rental house, there is also no point in keeping it also since it does not seem like you are not generating enough income to even cover repairs. 

What I do know is that those old windows are going to require custom replacements most likely!

In fact. the heading bellow the image states, "Gravity Furnaces Were Installed Starting in the Early 1900's".You will never ever know as much about asbestos as I do since I've been in the business for asbestos for about 30 years and we have so many government regulations and so many government inspectors breathing down our neck when we work on any asbestos abatement job because every mistake we make can result in horrendous fines and multi-million dollar employee and customer lawsuits.Did you ask if I am overstating health issues about asbestos?
