I have asked seller to split the $20,000 shortage, so deal would close on time, as agreed.

Borrow the rent from someone else if you are having a temporary shortage of cash. 

There was no shortage of discussion re "no such thing as no heirs".  

There's no shortage of qualified companies, but not all of them have the same customer service focus.

If you search “2% rule” here at BP, you will find no shortage of people with your concerns.

The trends show that the rents will level off in Denver once the all of the new developments are complete and there is not the large shortage that we are seeing.

There is no shortage of funds chasing repositioning deals here.

I would have to come up with the additional money to cover the shortage or lose my $25k deposit.Is this typical of a lease option?

No shortage of opinions here.I once posted on the the topic of missing owner, vacant and abandoned "orphan" houses with the expectation that a vigorous discussion about adverse possession would ensue, a topic for which I have a high level of experience.

Because there is a shortage big time for rental housing.. 10 years ago only 6% of all SFR's in this market were rentals. with the big chill on the economy that probably spiked to 10 or 12% compare that with the mid west were is 40 to 55% in most markets...And then you add out of state and out of area to the mix in the mid west and its darn tough on the C properties to make them. work and they are anything but passive you will be managing your managers all the time. and one day your tenant will somehow get your phone number and call about something not working int he house and get it fixed etc etc.
