I want to refinance my lender out and get some kind of conventional loan so I can pay down the balance with the rental income.

Do you think it would be enough to go get a EIN to fulfill this kind of lending requirement? 

I primarily need advice on:- Is it a good location for rental & What kind of tenants it will attract- How to rehab to maximize return w/ cost estimation- Conservative rent projection based on the rehabI need property managers for it, I tried to contact a few companies, but their response seems slow and I won't be able to directly talk to the actual property manager.Anyone can help?

If I negotiate seller financing, I am afraid to get into an agreement with any kind of balloon payment (just because it makes me nervous to have it hanging over my head) but I would like to negotiate a lower percentage downpayment than 20% so that I could afford to purchase all four (rather than two) under a warranty deed contract.

But if you're new and think your deal will need that kind of work done I don't think it hurts to use those more conservative numbers.

It just seems that for the kind of strategy I'm trying to pursue starting out (buy and hold multi family) there seems to be a lot more inventory out there.

Many investors are willing to close fast if it includes this kind of return, as long as they have clear title.  

However, the market is just kind of tricky here in Vegas at the moment and a lot of investments don’t make much sense.

There are houses that've been converted from a single-family to a duplex with a single meter but finding that kind of house in the area you want could be tough.

Even if you hired a designer as well you’d still save money versus paying the $50,000 .Searching listings online for homes that have sold as flips and see what kind of design they use or go to open houses of flipped homes .
