are there any restrictions?

Also I feel like its difficult to find credible vendors I can trust without there being a platform that gives access to reviews of what other note investors use. 

Is there anywhere on the app that has access to the calculators and forms like the website does?

Depending on your area and the specific property, the details change a lot - e.g. whether you can get access to the property, what they charge in fees, etc.

@Anthony McEvoy, we are using a single access point to cover both units of the duplex.

I’m also ok with making them wheel-chair accessible so the units would be a good option for seniors.

Good Morning Angela, I am a Realtor in Florida and I understand this completely. ( I am not one of those agents) Thank goodness, I would suggest not letting them know what you intend on doing as they only see $$$ signs, and if you are looking for something off-market then their commission will be less,  I suggest looking for the deals yourself through Zillow, Make me move is a for sale by owner, your county records, for pre-foreclosures,  do your research first, then contact an agent to gain access to a property you may want. 

Considering buying a small single family home in Dundalk area off Wise Ave for long term rental,possible flip...Any rent restrictions or other issues I should be aware of in that area?

At the time fridges were very small so food was out a lot & most of them came from countries that didn't have access to one.

Hi Jonathan,Several reasons, like easy access to background info on tenants and the it's bulk foreclosure program.
