Your best approach is to probably read through the posts there and search for specific questions you might have. 

What is your approach?

Instead, you either have to go with traditional methods such as asking family and friends for help, or you have to think outside the box and consider approaches like peer-to-peer lending and crowd funding.

Any thoughts on this approach?  

The present values being on an after tax basis.This is a rather simplified approach as there are other models that are statistically valid. 

I see. makes sense, especially on the equity and cash flow side of things.The thing is with those kind of cash purchases, how do I approach negotiations?

Some have said we need to be relatively low on monthly rent given the short period, others have said we can charge more because renters usually want long leases.Any particular marketing approaches or lease terms work well with 6-month renters?

I wanna to approach the owner but I am not sure what is the best strategy for me.

So you really, really need to play the exit game and look at each unit and say " If I approached this tenant for a rent raise and they had to get out how much per unit would I have to put in to land a new tenant?"

I think it's a good strategy, getting your feet wet with something that's manageable is a great approach.
