The downside is the rate will be floating, and likely higher, than a mortgage (but they are often interest only, so they payment will be less). 

You’re basically buying a Mobile home that floats/sinks and costs 10x to repair.

Anyways my estimate of the repairs needed on the building are between $50K - $70K which my general contracting business is able to float and absorb on the back end...

They have tried to answer this as effectively and expediently as possible (They were out immediately when ERP was still floating different versions of events, when they decided to make radio contact.)I would suggest that you look into Zelle or perhaps get a business account with your bank and pay for ACH payments.

And chances are, our property policy will close out and seek reimbursement from the Gas company.Bottom line, if my client would have to wait for 1, 2 or 3 years to have the gas company pay for the damages and lost rents, he would loss the property because he can not float that much $ for that long.That's the one I have this month:)

Most rehabbers are going to have their own Home Depot CC (or some other form of credit that they can use to float some of the costs). 

The owner is willing to float the note on the sale price if I get the rehab $. 

Also called a floating rate mortgage.Adjusted Gross Income: Gross income of a building if fully rented, less an allowance for estimated vacancies.

Do you float money to people 30 days interest free ?  

Try reaching out to some local wholesalers so you can see if there is anything floating around that is a good deal and possibly even some owner finance deals.If I were in your shoes (and I am) , first steps to freedom would be to eliminate bad debt until the only debt I have is sub 5% APR, find a motivated 4 plex owner and get the best conventional loan if possible and owner occupy one unit.
