I personally think all of the marketplaces are operating unsustainable business models, but some of them are decent at underwriting. 

DCF is definitely the more sophisticated approach, there is a good model on adventuresincre.com

Cant say much, haven't researched it.I have been in two other models.

Local banks have more a short term money outlook due to their business model versus insurance companies. 

That old school model I think is out the door. 

Ask for Floor Models or Landlord Specials.

@Cole Oraham TAMU has announced a hybrid model but I worry about all the international students that will have travel restrictions, or parents that won't allow students to return, or even worse sick professors (generally older and at much higher risk).

Hoping someone on here may be able to explain a little better.Lets assume after appraisals based on the LTV they are willing to give me $100,000 (i.e. arbitrary number to make things simple) either in a Line of Credit or as a bundled refinance.If my intent is to use this money to purchase say another (2) houses at $50,000 OTD a piece or a grand total of the $100,000 I plan to borrow.Using the LOC Model I know have my Line of Credit maxed out and (2) houses in the clear.

@Javier Rosales I'm usually not in the camp of "you get what you pay for" but in this case he is managing 1 unit for $30 per month and the other for $40 that is not a sustainable business model from him, really seems like the agent is trying to make the sale and let you leave once you find his PM services lacking, or once he becomes a better agent in a few years and values his time more his prices will go up.  

In my current model, the 5-6% range could work, but it makes it a bit lean due to the rising house prices with low rates.
