How do I go about doing a purchase contract in tx?

Not sure how legal it is, but you can ask for proof of funds for a couple months worth of rent. 

I was able to get the signature on contract because I educated her on what most investors will do (tie it up with contingencies to flip w/out closing). 

I have a property that I have under contract and one of the apartments was divided from another apartment.

Get a lease/option with the seller so you can legally advertise the property (because you have a lease). 2. 

Sorry alot of these other investors don't understand construction side of things cuz they get over their heads isn't fair to the one who's doing the work when they run out of money cuz they haven't dealt with anything of the sort & I'm tired of filing paper work over breech of contract it's old.

That money remains as the tenants money until due each month and can not be legally touched by you till the first of each month.

Is there any way for the management company to legally release this info to me without approval from the owner?
