Justin,Apartment investing is my expertise as I have acquired over 1,000 apartment units.With the price range you mentioned, you can get banks that can finance 75% of the purchase price.You can also negotiate with the seller for them to take back a 10% seller second.

Most realtors, if not all realtors, have a specific area of expertise and don't do the entire state, which is hours long.

@John Smithe - This is going to come down to the following:1) Your personal investment philosophy: your goals, your interests, your time horizon, your risk tolerance, and your interpretation of world events 2) Your unfair advantage: your skills, your expertise, your network, your resourcesBiggerPockets tends to bring together like minds and similar experience, so this sampling bias might result in concluding that a large multifamily in the Midwest, for example, is the best use of your funds.Ask the broad universe of investors the same question, however, and your answers will be quite different.Real estate might well be your best investment, but so might be starting a business, or picking stocks, or buying precious metals.  

Would there be a kind of strategy to solve the issue if the lender calls in the loan due to the deed transfer?

I think one of the top goal for the mayor is to solve the housing crisis in our city and build affordable housing.

@Cason Acor and others’ advice is right on—I would definitely recommend getting help from a broker with industrial property expertise in your market.

Your expertise in this area would be greatly appreciated.Looking forward to hearing your replies!

So finally I solved this problem last week and have been on a buying spree, but I have also heard that people would pay for someone to qualify for mortgages on their behalf so they supply the cash for downpay and (for example) I can just qualify for mortgages and in return hold the property under my name and get paid for it.

Given that I'm a vendor I won't make any recommendations other than to say that you should filter your decisions based on what is the most important thing for you to solve for right now. 

Hi Aaron,I don't know about the rest of the stuff, but here's a heads up if they "demouse the house".The carcasses and dying rodents will probably be full of poison (they typically eat a bait) and if your dogs get out and eat one of them or the bait, it's bye bye doggy.They have commercial bait boxes that are supposed to hold the dead rodents, but not everyone uses those.Good Luck with solving these problems!
