Jason,If they tell you they don't do HELOCS, ask them if they will simple do a standard line of credit.

If you demolished inside and they see it you cannot get a standard HELOC you will need to go hard money as most lenders are going to tell you that any worker who stepped on the site can lien the property and HELOC's do not use a new full title report, they rely on the title report of the last sale (again like I started with if people DIY record after closing it's a problem).

Many standard contracts state that if you keep the deposit, you are relieving them of additional liability. 

the more hands-on you personally are, and the more niche / creative / difficult the strategy is, the more the potential to cash flow (but also higher risk.)standard, professionally managed, vanilla LTRs in good neighborhoods basically don't cash flow right now with interest rates where they are.
