If you can't keep control of your personal finances, you are highly unlikely to succeed in real estate investing.

Personally, I am gearing up to buy as many as many SFH’s as I can over the next few months.Ft.

I have personal relationship with the owner of the project.

You need a pitch to win in a personal letter.

What's the name of the position or person who can tell me exactly a price range for what areas of the duplex/triplex need to be fixed and how much they cost?)

So, when you say they not do report on your personal credit report I guess you are talking about non-recourse loans? 

Ana,Based on experience and this market me personally I would avoid a HELOC for a few reasons.

Fingers crossed in 7 years I have not had to test my coverage, but in the area of my rentals a golf cart is expected with the rental.When they crash into someone else, did that person sign the waiver too ?

My PM used to have a person who did the payments and every year around Feb, she'd send out an annual statement for your taxes showing how much you got in rent, spent in repairs and management fees. 

Note ADU addition in a MF zoned area may be comped with a duplex but I personally think this is wrong as a SFH with ADU is not a duplex.- it is cheaper to buy a property with an existing ADU than adding one   In addition you would receive RE purchase financing.
