Also, banks are lending with lower leverage which means investors are required to bring more cash to the table to close.

I was able to secure a room for $50 at Sidecar Social for one hour, after which they will allow us to move to an open area/table. 

I can drop jelly on the counter, sprinkle crumbs around, and leave my plate at the table.

I have a deal on the table but I’m not sure how to go about completing it.

No comps means you are buying a "unique" asset, or taking a huge pricing risk in current market.

No under the table or untaxed income counts with me. 

As others have mentioned on here, every person's tax situation is unique and answers are not easily given over the internet and can often be incorrect. 

for a unique deal like this they might be more open, considering finding funding isn't as straight forward. just also be sure you have a backup plan for this property... what if they don't renew their lease at the end?

., etc. is going to make every property unique, but it would be great to come up with a rough rule of thumb that will allow a conservative estimate.

Each person has their own skillset they bring to the table.
