It is very stable and diverse.

It's a stable market given the medical influence in the city.

This is a very common way for people to investing using their retirement accounts.

How would you approach this situation to keep scaling while staying financially stable?

Here’s some context: Property 1: >$100k in EquityValue: $325kDebt: $220k @ 2.88% (30-year fixed)Property 2: >$70k in EquityValue: $325kDebt: $252k @ 3.38% (30-year fixed)Extra considerations: - I have $15-20k liquid to use for any of these deals- My current job is relatively stable, but not high-payin- Current properties in TX, living in NY, looking to invest in Mid-West (crazy, I know)- No other debt obligations besides the two mortgagesUltimate goal/timeline: Though a bit ambitious, I’d love to build up the portfolio to 10-20 units in the next two yearsI understand that any/all replies aren't financial advice; all ideas welcome for information purposes. 

This active income can help me fund my retirement as well as help me get reimbursement for home office and health care premium while lower my tax liability.

I have some crypto gains I’m really looking forward to dumping into a more stable asset class and hoping this can help me defer the taxes on the growth. 

I'm a retired engineer and have been successfully using income from these houses to support my retirement without dipping into retirement savings.I'm transitioning my business from rentals to a franchise and would consider selling one of my houses (5 br/4 ba - the other houses my son while he's still attending).

Fast forward 20 years: I now have money in the bank, excellent credit, live modestly on my own, and run a business that’s doing well.Unfortunately, I wasn’t able to save much for retirement during most of my life.

We don't have kids (might in the future), my husband and I are young and healthy, have stable high-income full-time jobs, and just put in a lot of work to both properties so don't expect huge expenses in the near future.
