Using personal funds for entire house purchase - it is smart?

[Z Smith]

Hi there. I want to purchase my first SFH to rent. Purchase price will be around $100k. I'll receive at least $1k month in rent. I am 30 y/o. I work from home full time.

I am having a lot of issues trying to work with banks for a loan and find they slow the process down considerably. I am wondering if using my own money to purchase the first home would not be a good idea. 

I have over $100k in personal cash I could use for a deal. My thinking would be that I could purchase my first rental and have 100% equity, and then use this as leverage to receive a bank loan for another $100k house about 6-12 months later; all the while any rental income less expenses can be put into a savings account to be used for a next deal 6-12 months out - and repeat this process until I can get to 10+ SFHs.

I welcome the conversation on this topic from this community. I know some people would say never use personal cash, but since this is my first deal it may set me up to receive loans easier in the future while making more money on the first deal to help pay for more purchases.

My second option would be to use my personal home as collatorel but that scares me frankly. While I was lucky enough to pay my mortgage on the home off in 2014, leaving me with a $200k asset to borrow on, I am just not sure if it is needed for my first (or second or third...) deal.

I appreciate your thoughts...
