If I just allow it, the other tenants in the building will take notice, as this is highly unusual.

All with the same opposite corners if possible.If there are any unusual features, take a shot. 

Don't forget to check for unusually expenses like HOA, trash or utilities if the units don't have separate meters. 

That absent any other unusual facts.

I did get one back this last week that was 5% over contracted price, but that was unusual to me.   

They are appraising as 3 bedroom, not sure how that works. 4) The AC is 16 years old and will probably need to be replaced soon 5) The hot water heater is also old 6) Crawl looks clean but there are rodent boxes down there-like the ones you see near businesses so wondering about that 7) The house was in disarray, needs new carpeting and paint and some work in kitchen, no hardwoods.Would need upgrading if re-selling 8) master is odd, no linen closet in bathroom but there is one in master bedroom 9) no laundry room- they have the laundry in a bathroom in the kitchen. 10) The entry is odd and unusually narrow, as if they enlarged a room and it encroaches on the entry. 11) bathrooms are small.

First, some general tips for you on red flags to watch out for:- Asking for a large loan application fee or other fees upfront- Unusually low interest rates for a hard money/private lender (real hard money/private lenders aren’t loaning money at 4-5% but fake ones usually advertise those rates)- Email communications with really bad English/grammar indicating the sender might be from out of the country- Claiming they loan nationwide in all 50 states (most non-bank, hard money/private lenders operate in only certain states and don’t lend nationwide)- Claiming they can do loans from $5,000 to $50 million (most lenders that will loan you $5,000 can’t do a loan for $50 million, and most lenders that can do a loan for $50 million aren’t going to bother doing a loan for $5,000)- Offering to send you a photo of their drivers license (fake lenders tend do this to convince you they’re legit but I guarantee you it’s not their license they’re showing you and a real lender would never do this)- Not caring about your qualifications or the merits of the deal (basically willing to “approve” you no matter what you bring to them since they know they’ll never actually fund it)- Terms that seem just way too good to be trueThat’s just a few things to watch out for.

However, the ones I've talked to so far (Chadwell Supply and GE Direct) were surprisingly expensive for installation services and made it sound like asking them to install and haul away was unusual.

However, two weeks without interest would be highly unusual.

Its not unusual to have a condo on the market for a month or two right now.
