Now that being said the smaller the loan the less significant and at 200/month its probably less significant but the overall amount of money u can get for for house loan be $200/month less. which equates to *does some light math* about 15-35K less in loan amount.Im trying my best to hold off on the car loan till I close *June- fingers crossed* or just buy a car cash.Good luck!

As far as cash flow is concerned, that is a mathematical equation that can be easily manipulated.  

This scenario is amplified when you have one customer for that one property since your one tenant equates to 100% of your customers. 

For me personally I don't think I can do it though, as I'm in southern california (and tied down here because of school) Around here I couldn't offer 20-30% below market without smearing my name as that usually equates to a discount of $100-200k or more.

or just lumping it all into one.. that's the big killer in this equation in my mind...

On one end of the equation it would probably be a no-brainer that it would make sense if you were buying all the windows at wholesale and either installing them all yourself or paying someone hourly to do it.

If, instead, I kept my current house in my name, and just leased out our spare bedroom as an office to my LLC, I believe I could count a portion of the rental income (75% if I remember correctly) into the DTI equation, thereby helping my DTI for the new property.

Second, any HOA fee equates replaces a portion of a person's mortgage payment. 

We have capital, and I'm not exactly sure on how the numbers look like investing into a 4plex, but it's possible we can make it.House hacking is definitely out of the equation for us.How would you feel about just buying a 4 plex straight to 20-25% down without owner occupancyAlso I'm surprised you mentioned you would do a 4plex first as someone whose going into their first investment with 0 experience, but I'm open to anything, I have even thought about constructing a duplex from the ground up, but it seems like that's a long road for a first timer.

@Rina Amir@Radhika M. is correct with her guess in that the equation you're using is assuming 30% expenses, leaving 70% of total income as NOI.
