@Dustin RuhlWhat you should also look at is default rates vs foreclosures as lenders have moved to alternative resolutions besides foreclosures due to lengthy foreclosure timeframes.

You can use the Blumberg A-55 'New York Apartment Lease' these are standard forms that you can buy online or any stationary store (probably cheaper since they sell them loose)...I own two NY co-op rental and use it in both...another alternative if you work with an agent is using REBNY form which is very similar and would agent probably suggest with no charge to you.In addition I follow my old landlady (an RE Agent) practice of supplementing it with a rider (copied hers) in which I stress/modify/add term which are important for me (for example that tenant cannot Airbnb the apt).The co-op is a company which have their own interest which not necessarily align with yours...it just happen that sometime they allow you as a shareholder to sublet your unit.   

Other creditors would balk at that preferential treatment and insist it go on the open market to ensure maximum recovery on behalf of other creditors.

Alternatives include renting short-term or long-term, building a house or even getting an RV.

Any alternatives?

I attended a fortune builders 3-day seminar, I was not looking to sign up for the Mastery program, but while doing some searches online for alternatives I stumbled upon Realeflow. 

I'm doing some research into the feasibility of starting a non-profit that helps people with a certain rare type of cancer (of which I'm a patient too) get to MD Anderson for treatment.

Hoping there are some alternative options to overcoming DTI and house hacking with multiple conventional loans.

@Alvin Uy have you considered alternative asset classes?

My personal pathway is going to be to get one with a conventional loan, then use alternative methods over the next 5-10 years to try to accumulate 5-10 properties and then use all the cash flow to pay one house off at a time until they are all paid for.
