I imagine both groups probably do very similar things and are equally valuable.

It sounds like these people are starting to be your friends but the landlord-tenant relationship is kind of a false friendship because you are not on equal footing.

It is very important to file an extension by the March 15 or April 15 deadline, depending on whether you are a business or individual, because not filing an extension will result in a 5% per month for failure to file penalty, but it is equally important not to file a full tax return if your exchange is not completed by the applicable filing dates referenced above.    

I'm a veteran so I'm using my post 9/11 which equals ($3700) month which I only get while I'm in school but will be getting for the next three years.

This means you would need cash (or some form of cash substitute) for the difference between the Purchase Price (hopefully less than or equal to the Appraised Value), and the loan amount.

When I do that math on estimated rehab and ARV, the 50% of profit doesn't even equal the 20% mark up of construction costs that I should be getting paid to run my business.

If you have wood trim and floors not all neutrals look equally good.

In most cases aren't full value deposits (equal to one month's rent) going to be forfeited by the tenant anyway in order to resolve whatever repairs they are responsible for?

Or should I require him to pay the deposit and maybe give a discount on monthly rent equal to amount of work done (monthly discount applied until amount is credited).

If I have a broker representing me and we come across a seller that has does not have representation, my broker can all of a sudden change from having a responsibility to me to a responsibility equal with seller.
