I agree with Mike - I think it depends on the exit strategy.It feels very tight for a flip, even using Subject-To to finance it.It might be a good rental  or seller financed opportunity.   

If you're not as picky or on a tight budget there's always crowdfunding. 

Since the timing involved (30 minutes) is so tight, this is a tough one and you really will have to look at the contract and at how much you want the property to decide if it is worth a letter from an attorney to the seller's agent saying you are enforcing your agreement.On one such property, a long time ago, I wrote a letter to the broker of the selling agent.

The popcorn ceilings is another one that people do not like.I would just sit tight and wait.

If this is true, it's likely the supply of affordable housing in Providence, Warwick, Pawtucket, West Warwick, Central Falls, North Providence, South Providence, etc will remain extremely tight.

Still think this one might be too tight for this intended strategy. 

Maybe on a small scale, but in a tight market, buyers are slightly hesitant to give anything away, be it to a colleague, lender, or anyone in between, regardless of the likelihood.

If the  market is tight, they are going to offer a price that is competitive.

if you like the deal just bring in the required equity and close.. not sure what the issue is.. unless your capital constrained and if its that tight then you may rethink the whole thing as stuff happens with flips.. you need a really good amount of reserves to be doing this safely.

So rents and home prices movements can diverge, and rather dramatically.In the current real estate market it seems that in most major markets across the US there's a pretty tight correlation between rising rents and rising home prices, some markets even in percentage terms (which I find somewhat remarkable).
