For contractors, I'm looking to locate reputable full service and specialty (plumbing, electrical, etc.) companies.  

We build approx. 20 homes per year, and are working to establish relationships with reputable nearby vendors.Specifically, we are having difficulty finding the following trades:- Exterior siding installers- Brick installers - Plumbers- FramersWould love to share resources with someone else building similar product ($1M to $3M range) for subcontractor pool, pricing expectations (e.g. $/1000-brick for install, $/SF for framing, etc), etc. specific to this region.

The key is to find a reputable one. 

I would take into consideration what your tax consequences would be.

If you could afford a $400k property in Boston... would you stick to a studio apartment in a good area of Boston or go to some of the cheaper areas where there are longer commutes and more of a reputation for crime?

A reputable company sells you the home fully renovated and provides professional property management.

So yes, you can have all units empty as a consequence of increasing the rents but once you fill them with better tenants, those tenants will stay longer and not trash your apartments.Let me give you an example.

These are usually small lenders.Suggest you find another lender LOCAL to you with a good reputation from other borrowers in your area.  

On the tenant background information however, you should at least be provided with the lease and the names of your tenants however, we nor most reputable PM's will share sensitive tenant background or contact information with owners.

Can that have any negative consequences for me or my property?
