I am very proficient in multifamily in Houston, feel free to message me, and I will gladly help you—all the best, Vincent. 

English proficiency is big and a neutral accent for calling.

If you grow to a number of rentals and work at it things will even out and as you become proficient you will feel confident that you can meet or more likely do better than those estimates. 

I am deciding between building my own site on Weebly (I have used Weebly before and am pretty proficient with it) and utilizing Carrot or LeadPropeller.

Once you become proficient in comping and knowing what your “ASIS” offer needs to be, you can start lead generation to find opportunities.

Their website has all the signs that it was created by someone from outside of the US who isn’t proficient in English and has no idea about lending (their Loan Term and Conditions are laughable).I’m not certain if the scam here is to collect (and then steal) your personal info (DOB, SSN, etc) requested during the loan application process, or charge you the upfront loan origination fee they refer to for a loan they’re certain to never to fund.

I suggest that you practice running numbers on a handful of houses that you have no intention of buying ( it takes the emotion out of it) - get proficient at ARV and repairs, those are the two places people get hurt in this business and oddly enough the two numbers that as investors we are so willing to trust and not verify. 

Once anyone gets very skilled, proficient, successful in any profession they quickly learn what takes up a lot of time for little return and is a big headache.As an example I get contacted often for people interested in commercial real estate.

Does anyone have experience with this process or proficient with google sheets? 

I have concentrated my properties in one area and have become very familiar with and proficient in that area.
