The next step would be to survey the property and submit the necessary applications (preliminarily short plat). 

The property is owned by Bank of America and has a fixer upper home in the front with a mobile home in the back of the property that has been rented for an unknown amount of time.Both a survey and title search have revealed that the mobile home is on the property and has been detitled and joined with the property.Has anyone has run into this type of scenario before and have any tips or advice to give?

Did you have to get paid membership on BP to find them?

Get a membership.

.- Survey - I don't think this is really a thing done everywhere, but around here, it can cost around 350-400 for a normal city lot to be surveyed (greater for more land) and can be pretty expensive for the sellers.

We don't really have enough demand to warrant a skip trace membership, unless there is a reliable site that allows you to pay per inquiry-  Any ideas appreciated!

Do you have a second for a quick market survey?"

You might be better off that you learn more about  partnership memberships where you stay in control and just offer them income without being into working on the property's day to day operations. 

At this point I’m not finding the info I need or much  help, so the upgrade from current paid membership to pro doesn’t seem worth it.

Recent price reduction of $120K and we got it under contract almost immediately after it was listed at the new lower price.We have done local rent surveys and we think we are competitive.We're still in the Due Diligence phase right now, and are getting: Appraisal, environmental study, HUD statement, utility details, insurance, financing.Anything that you think we should be considering here, either about this deal or about getting into an office building in general?
