If you build a solid machine to hit the brokers on a constant basis (by phone and email) then that will pay dividends.

Many of your local smaller banks and credit unions will be still in business and lending, but you may have to make more phone calls to get to the ones that are lending. 

I always read title, but since we're not experts in title I always tell my clients the best way for them to do their review is to call the title company and ask a rep to go over it on the phone with them to look for any red flags - that way they're putting the review in the hands of an expert.- Your contract probably has deadlines for various things for the buyer and seller (inspection, applying for financing, etc.) - it's a good idea to go through the contract and make a Timeline Worksheet that you can provide to your client so you are both on the same page.

These are scum of the earth who think the world owes them something while they contribute nothing of value.So an update to the situation:After a significant amount of research and phone calls to sheriff, multiple lawyers, police, court house and a few fellow investors, I gave them an unconditional 3-day notice to quit.Once the courts open, I can get them out...once the back log of cases gets worked. 

I'm still getting phone calls and post cards asking me if I want to sell it. 

The tenants left the place with pee smell and broken window and we spent over $15000 fixing the place up removing floors and repainting the whole place, a brand new dishwasher used 5 months was thrown away.

If no credit score, you can still get an FHA loan using alternative credit, such as rent payment, insurance payment, mobile phone payment, utility bill payment, etc, but you will need to find an FHA approved lender who will accept alternative credit. 

Even if they provide supervisor direct line, try and reach them through the publicly listed phone from the website.

I would start with a direct phone call to the tenant (father, on the lease).

as a new agent you need to decide where you will hang your license,(broker), you dont work on your own, part of the idea is than an experienced agent will over see you and help you work,there are many companies out there, interview with a few, let them talk, most would rather hear themselves anyway, steer clear of more independents that boast letting you keep more, not for newbees, i started out with national chains till going to remax after many years, the chains will will have additional training for you, I also mentored two other agents after hitting elite status on nationals, be ready to give some of commission for mentoring, dont volunteer it up front, you will have many fees to pay starting out, sometimes you can also be an assistant to a major agent too, you will list thru a multiple listing service that other agents used to find houses, public too, they cost also for membership, on your own you cant list on craigs and do open houses, there are some who only list and some who only sell, and some inbetween, if you are lucky enough to get both sides, suggest you get someone else to take buyers side for transaction if you have iron clad relationship, or stay neutral, some list only to take buyers elsewhere, one house one sale, one house many buyers, what ever you do stay intouch with listings, plus with national agency lots of experience, lots of ads, national website, referrals,traing avail if you got in this to work from home and make a large commission right away you got sold, fees will eat you up, sales take time, money and experience, some get in it to buy their own, that is an option too, do lots of phone time, stay friendly with all in office, avoid politics of all kinds, do rentals to pay the fees, they can  turn into buyers, expect to make first listing within 3-6 months, sale 6 months, till up to speed, my standard was 2 of each a month, some more some less depend on season, can tell you stories.... doing floor time once had buyer walk in, said wanted to spend no more than 2, turns out was million, no one wanted to do floor time, also my first listing was a real frank loyd wright home, other agents would me give their rental lookers, be willing for all, I worked in area of NJ where a famous golf course is, was one of few that belonged to all 3 mls, so had advantage, a $1500 corp rental relocation will some day buy, get to know the relo person, we used to give nice gifts to clients, make it something they will see everyday not flowers or candy
