In general you can't double dip and charge the old departing tenant while alos collecting rent for the same unit from a new tenant.

It's relatively easy to sell land with owner financing, and so far I haven't had any trouble with collections.

They likely collected these upfront to determine the best loan product (likely wanted to compare with a full doc loan).

We have extensive land-lording knowledge and marginal rehabbing/project management experience; keep an eye out for someone you know of  that is looking for capital partnership on rehabs-flips, sub <-100 acquisition market.Thanks.

If there are common areas in the commercial property, then sure you would need to do the accounting regarding who pays what and what's collected among the various tenants. 

If you are taking extensive time managing, spending money on gas, repairs and maintenance you are under water.

Without knowing how long your process takes in your state, the best I would do would be to offer to loan her the money at some interest rate, and still follow through on collecting everything she owes.

(Agreement with your client that grants you the authority to collect on this alleged debt.)

For Aug rent, it would have been prorated.How extensive are the renos to the vacant unit? 

Also I did a tiny bit of research and it looks like the "insider circle" is actually just a collection of lists they compile for you.
