For the most part, if you have a credit score and your loan officer submitted your loan through desktop underwriting or loan prospecting (automated programs used by originators to qualify a borrower through Fannie Mae and Freddie Mac guidelines for conventional loans or FHA loans), and received an approve/eligible, then you should be ok with just the two trade lines. 

You can only borrow against market value, which is going to be calculated by an appraiser (or sometimes the bank if they desktop appraise). 

I think I have to go on a desktop to access events it can I do it through the app?

More on the technology side, I would like some type of app that would let me easily keep track of people I contact and other information, like phone numbers and websites if they were talking about them, and I would like it to work on my phone and on my desktop computer. 

No - this has to do with the TERRIBLE BP desktop/app interface.

I just bought a new HP desktop for my business and when I try to use google maps/earth or something similar I feel like I’m led down a rabbit hole to download extensions and then it never works for me.

For accounting/ book keeping, check out quicken home & business desktop software, which has a rental module to allow you to download all transactions from your bank/ credit cards, then tag transactions by property and categorize them by IRS expense category.

Use the hard money lenders correctly, run your numbers before you purchase, and every time new numbers are available (desktop appraisal for ARV which the hard money lender will require, written quote from contractor for repairs, etc) ensuring you have at least a 100% return on capital gain, and will get at least a 10% cash on cash return after tenant in place and refinance. 

On a desktop, click Performance Tab - Visibility - Listing Page views and scroll down. 

@Neil PradhanangYes, RPR is another one, but I only use it on my desktop so that's why I didn't mention it here!
