Hi all,
   I am interested in building a 3 floor, 9 unit (first floor retail store + 8 apartment above) building in Pittsburgh and received a quote for the same by a local builder. Is there an experienced builder he...

He acted like the world has conspired to keep in the consultant position! 

I have been a long time stalker and daily reader/ listener of BP, but never posted myself.

I suggest you consult with your broker.

You will probably need at least 3 just to pay for your entity and administrative costs.Of course, you should consult your advisors as I’m not a CPA, attorney, etc. but sharing my experiences.On the lending front, I would only go with Hard Money or Private money if you are planning to add significant value (buying under market would count as @John Koster pointed out).

@Ishmael Vir Find & use a good, experienced attorney in your area who has been working with wholsalers for a long time & pay them to write one for you.

At some point it will be in your best interest to consult and enlist the service of an attorney, start building that relationship now, figure out who you want to work with and who you don't and start building that relationship. 

There are multiple vaccine efforts ongoing, are there other coronavirus types that have been around for a long time.

 You should review your state's rental property laws or consult an attorney.Usually the state requires a certified letter of lease non-renewal to be sent to the tenant's residence 30, 60 or 90 days prior to the ending of their lease. 

I don't think there will be a huge crash like the one we last saw, at least not for a long time, that was a rare event, they don't usually drop that much when they do drop.
