What does a wholesaler do if they cannot find a buyer from their list within the time limits dictated by the contract?

My friend who lives there says people are constantly posting asking for homes to rent, but the inventory is so limited with long term tenants. 

I know and like that the applicant pays Cozy directly for the cost of the checks, so I don't have to handle the money. 

In general I’ve found that new builds are least expensive, limited/hard to get, the better amenity places like Windsor Hills are a bit dated homes, newer places have smaller amenities.  

The main problem is PenFed allows applicants to own only three total properties (including primary) to qualify. 

I am not sure how big the property is, but many cities have occupancy limits based on the number of bedrooms.

As an investor with RS you only have a very limited time to do your due diligence and you have to rely on the data RS provides. 

Am i able to deny the applicant with these findings?

I thought that sounded steep, but none of the applicants hesitated to pay including the one with a 450 credit score who was well aware of our minimum qualifications.

Her reason for investing is she likes the area and will plan to visit in the winter and also to help us out as we are also considering investing in another multi family property and have limited cash reserves to fund both deal.Thanks in advance for any advice.Regards,
