Once I got completely consumer debt-free, my disposable income skyrocketed.  

When talking to new folks it boils down to the big three for me below:Previous experience (what do they know that will be useful)Network (who do they know)Resources at their disposal (what do they bring to the table in terms of capital, time, information, etc.)While many investors love working with new folks it often boils down to "what can they do for me".

If you're investing with people who are gambling with their baby's next meal, things can go south much quicker than if you're investing with people who have disposable assets and income. 

You need to look at the (personal property disposal laws) for your state.

But you'd have less disposable cash and your cash flow wouldn't look as good to other banks for future loans.

I just cut it off close as possible with circle saw and spliced on and supported allIts easy to dispose of bad stuff here yet,,,thats why it should be disposed now if possible and in making your floor solid.Double bagged is all required and hauled directly to landfill with appointment.

After the tear down you'd have disposal, building, and landscaping and not to mention a dozen steps inbetween the obvious ones I've mentioned. 

Go to the plethora of meetups and REIA's in the area to learn about the in's and out's of investingAlign yourself with a good local Realtor who deals in multi-family properties (there aren't that many out there)Find yourself a local lender that can guide you through the myriad lending programs at your disposal.  

Use the free tools that are here at your disposal! 

This is very locally dependent....type of construction, disposal costs, etc.
