Although we can't be for certain on the payment history of the the tenants, we did find out that one tenant has been there for 13 years (unit B) while two tenants are getting their rents heavily subsidized by the government (I might add unit C is abandoned but the government is paying the rent until the lease is over in a few months or so I'm told and unit D is the one being evicted - he hasn't paid his portion).

@Imthiaz Ahmed The 4-unit limit is I believe a Fannie Mae and Freddie Mac limitation: http://www.freddiemac.com/singlefamily/news/2017/1128_loan_limits.htmlAnything beyond that, and your investment is no longer backed by the government, which is why you can get the lowest rates on conventional loans (i.e. less risk).The question to ask yourself is, is a commercial loan all that bad?

@David C.The government needs its money.

(This should govern your leases as well) you may not need to consult with an attorney JUST for this issue....It's never a bad idea to run things by a real estate attorney anyways.

I only invest in areas where the local government/communities have good long term strategies in place.  

Check your local governance for how long to retain.In California, for a written lease keep it for 4 years minimum from the date of vacancy. 

However, I've also heard that the government is lowering their voucher amounts so that they can provide more vouchers to more families.

i thought all these agencies are sponsored by the government ?

Then buy something .. look you must take action or you’ll be like the other 90% of people over 60 that are living on government programs .

1.Ask for a copy of their standard seller side and buyer side closing documents2.Ask if they close any non-traditional type transactions you intend to use.3.Ask for a copy of their standard fees, and if title policy rates are not set by a governing body4.Ask about insurance premium rates.5.I would ask them if they are investor friendly.6.If they double close and if what do they, ask what do they charge for the 2nd close?
