We are planning on keeping our prices where they are for the first year in order to build a solid reputation before raising them a bit. 

I have since had them get water on the floor and bring down the living room ceiling (something they deny, despite the plumber telling this to me) - I haven't made them pay for it, instead I had another plumber there and am now moving on to a roofer because there's nothing wrong with the plumbing.

And they can only count the ones where you were on title because that's something that can be verified from a reputable third party (i.e. county records).However, you can still get hard money loans as a brand new investor, even at 10% down. 

Do you have a reputable company who is looking for investors?   

Hi All,I'm looking for recommendations for a reputable mason who is knowledgeable in basement waterproofing.

They have recently spring forth as two new iterations/websites to try to escape their reputation and keep ripping off investors- The other two current names are Real Estate Federal, and Real Estate Leads and Appointments.

My plumber disagrees and says I should be proactive and do the fix to prevent a larger issue in the future.Thoughts on if this is the condo board's responsibility and whether I should cover the costs for the fix?

Always find a reputable GC to bring with you, and make sure he gives you an “all-in” full reno estimate.

But our building is pretty high dollar value and I have to have a reputable firm do it for this particular situation.

If you're willing to do the legwork, you may be able to find someone to do the slab cutting and excavation, then have a plumber come in to do the piping work.
