I threw the last crowd out of my daughters home because it was a mess.I mix Fabuloso in with a chem cleaning agent we get in 5 gall pails from a local chem company as little else was working on tough stains, like red wine, dog & cat etc etc.

Verifying last 2 years of rental history very important!

Think of it from the PM's perspective: if you were them, would you deal with the significant headaches of a C or D area (non-paying tenants, trashed properties, crime, police calls, etc.) for a 10% cut of a single property (probably just a few hundred bucks a month) ...I wouldn't.To make matters worse, the property isn't appreciating (because it's in a low appreciation market, or even a depreciating market), and the tenant pool is primarily made up of people with bad credit, low/no income, and a history of property damage at the previous places they've rented.

I am not sure how long each property needs a rental history in order for it to be counted as income, if they only count a certain percentage of this income, etc. 

Sounds like they're still trying to get their arms wrapped around how to underwrite since there's so little history with STRs being done in larger MFRs.

If they provide you one, I would still say I am getting my own.I would ask for full demographics of the area, including incomes, home prices, education levels, crime levels, etc.I would want to see full tenant application and any pertinent backup verifying income, employment history, landlord references, etc of the in-place tenant.I would want to talk to the property manager, if they are coming with the property.  

I would start with some education, building your work history, establishing credit, and saving money.

Look at the history of the house on Realtor/Zillow/Redfin and see how many times has it sold and at what price.

It could give you some clarity on the situation.This has been the longest cash out refi on an investment property in the history of mankind.
