It's a good rental market for buy and hold.

I buy and hold.

It sounds like you know how to avoid this in the future, so what to do with the situation at hand?

Having professionals we can call to see how backed up they might be factors in as well - if we can't get a roof done ASAP, that holds everything else up if we have a leak so again, more time, more holding costs, lower ROI.Unfortunately I do not think there is a magic metric that can tell you if the deal is a winner or not. 

Supposedly they have had a deal for me in Florida that has had title issues that has been holding it up from closing.

Since you're using hard money for your fix-and-flip, make sure you also have reserves for holding costs and unexpected expenses.

That will give me a gross profit of 20% minus holding and commissions.

We are considering building and holding townhomes but need to determine the costs.  

I’ve bought 10 SFR buy n holds in the last 12 month that cash flow ok.

Hello Dana, For that purchase price in Brooklyn, NY, you could be looking at considerable unknown expenses at this point.If the property is occupied, you'll have to factor in attorney fees and holding costs while you wait to gain access to the property.Furthermore, you could be facing additional costs related to title issues: open permits, violations, liens, judgements, etc.
