I also gained some experience with Landlording and fixing up a property to put it on the market.Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

Research your state landlord tenant regulations.

Health and Hospital probably got it through the Landlord registry or the tax records.

Im really new to the landlording game, and im trying to get clear information on how to properly and legally deny a tenant application.

Take your time, remember the tortoise and the hare story.I would start of by renting your parents house and see if you like being a landlord for 1 year. 

I know your goal is to eventually have this as a full blown rental so make sure you are able to get rental premiums to cash flow for years after.Other considerations is that you need to make sure you learn your landlord-tenant laws asap.

See if they have any special programs.)Don't be disappointed if they want you to have another $10,000 or a longer work history or if they seem skeptical about your ability to be a new landlord. 

Pursuant to this law, if a building doesn't have a residential certificate of occupancy, which would require landlords to bring fire and safety codes current, they can't evict tenants from living there.The celebs' building doesn't have the required certificate so they can't be evicted.They owe the landlord $120,000!!!

Boston Real Estate Guild is a great one, there's also a Cash Flow event hosted b y Boston Landlords in Back Bay monthly if you want to check that out. 

Been a landlord for 5 years so far and have 20 units so far.
