Well turns out the Reason that she was late was because the post office returned her mail which had my rent check in it.

Also, do I need to return the balance of the security deposit within 30 days of them vacating or within 30 days of the end of the lease? 

Make sure you keep each unit's security deposit in a separate interest bearing account and that return of the sec deposit includes any accrued interest.

Too much out of pocket $ for the return.

I even tried to cut my losses and told him to keep 7k for a half days work of demo and return the other 8k.

We actually sold one hat had been in the family for a long time due to the pathetic returns we were getting.

You'll get more accurate advice and answers, and they will probably be more willing to work with you and guide you in the right direction if they have documentation to look at (tax returns, W2s, amounts you paid for each property, taxes, insurance costs, estimated rents and completed values, etc).

@Souji Kumar Do you think $200 per month is a good enough return to borrow $100,000 in an area that you know nothing about?

He sent me properties that included scope of rehab, expected returns and costs, and several pictures.

Incredible returns, no maintenance needed, and you can buy/sell all over the country.
