I am a construction contractor as well.the scenario in front of me:deal 1: 3 commercially zoned tracts (3.6  acres) in a business park used for office/warehouses/stack yard. price for all three (contiguous) tracts $150k. within 1 mile there are similar tracts going for $300-600k. this is a killer deal on dirt. 2 plays here...purchase and then flip lots only separately for more money, or spec build to sell or lease out commercial buildings. current realistic potential lease rate for a 40×80 metal building with small office is 4000-5500k monthly. construction cost would be about 150k. building and land value around 500k on low enddeal 2: value add commercial medical office/general office space. price $200k Reno cost needed 10-15k. would lease at 2600-3200 monthly.

CapEx can be a cash flow killer, but don't let yourself get scared away from investing due to CapEx!

We always do a quick walk through to decide if there are any obvious deal killers.

As I have learned the hard way, CapEx can be a killer for inexperienced investors.

I have run the numbers on these, the deal killer for a condo is the HOAs the smaller ones are $336 a month and bigger ones can be $500 a month.  

I would not consider this a deal killer.

15 year mortgages are DTI-killers, which can turn into unexpected deal-killers.  

There's MANY reasons I don't like duplexes:Generally, lower class tenants (and that's a deal killer)You're dealing with a commerical property... harder to buy, sell, manage.Your management and maintenance will TRIPLE over a SFH of the same value.SFHs hold value better and you sell them to an end user, NOT and investor..... except typically new investor that are not skilled yet, try to buy duplexes.Also, tenants talk to each other... last thing you want.

If it is headed towards the property in question you may have a few months or few years until you see killer appreciation. 

If everything is still a go at that point, spend time on the compliance to make sure there are no deal killers.
