If they give me a gift of say 50K and file the appropriate forms to show that it is not a 'loan' in any way, are those funds acceptable for a down payment on a conventional investment property loan?

The realtor did a great job and the owner gave me a rehab estimate within 2 days of the offer being accepted.

do not accept partial payment as it muddies the eviction.  

Accept mediocrity only if the alternative is disaster. 

Because someone like me who has properties for sale, will put that letter in the file for that property and maybe six months later I will give you a call and make a counter or accept your offer.

I'd like to know your thoughts and experience on accepting rent payments.

Now, the seller and her agent have accepted my offer.

I told her I didn't accept partial payments and I would expect payment on the 4th (3-day grace period). 

I'm working on a deal analysis for an REO property & was wondering the odds of the bank paying for closing costs, assuming they accept the offer?

Investors are willing to accept a lower cap rate on a property because they feel the property has the potential to increase in value over time.
