The 100k essentially becomes your down payment. 

It will of course affect your tenants directly, and your house meter on multifamily.Disclosure: I volunteer for the EV Charging for All Coalition, a non-profit working on building code policy for multifamily EV charging.

As you already touched on, you won't have a down payment as a Veteran.   

- we have a separate business bank account that we could receive payments from - we have tracked all renovation costs and expenses, though they were done personally and not through the business

Mostly I just want a platform that reliably works for pre-screening, credit, background, leasing, payment, and reporting maintenance issues.

Include not only the mortgage payment but also taxes, insurance, property management fees (if applicable), maintenance costs, vacancy allowance, and any planned capital improvements.

That isn't enough equity to move the needle now and since you are on a 5.75% FHA, your payments are probably still pretty high comparatively which might cut the ability to save more.

We later sold the property on seller financing terms, asking for $139,000 with an $18,000 down payment, also spread over 30 years.

I get a percentage or previous agreed payment.
