Also what could I be getting myself into that I’m not thinking of or simply bypassing here..Who is expected to pay for this ordeal in this type of situation..and for what exactly?

But, to your point, Stuart, I think the ones that are marketing specific outcomes, beyond just you will learn about multifamily investing, are more likely to be the ones that simply cash grabs by the educators, themselves.

An investment club, like some on these forums, that are simply bringing people together to review other people's deals are generally okay.  

First however, I think it’s important to know why you’re interested in a mentorship program first – before you can adequately determine its value or worth.

I suggest stepping back from what has happened thus far and determine whether you'd buy this deal as-is.   

The mentor will have an opportunity to know you, see your determination and will, and then decide to pour their time and energy into helping you develop.

If a lender bases the loan off the property's rental income, I'm curious how do they determine that amount of rental income?

It shouldn't be a recurring scenario (or it looks a little less "accidental") but in cases like this, your job is to simply have the correct intent, see what you have done to demonstrate that and build your case.

We have had a few quotes, most cannot just simply mud jack it, but would have to completely re-pour them.

If there is complaint, simply I will find a money orientated contractor who will understand.
