You won't be remodeling all four units at once. 

This will also possibly allow you to value-add by both remodeling and possibly adding ADU's. 

Say that the property needs $100k in renovations but, based on your research, after remodeling and increasing the rents, it will appraise for $850k. 

I plan on getting a 203K Loan to perform a major re-model on all 4 units and eventually convert them to 2 Bed & 1 or 2 Bath.

My single tenants can easily find alternatives when they get their notice that I'm quitting.For tenant proofing, I try to make remodels easily replaceable.

Currently the area is a little rough but many remodeling projects are taking place which is part of what is helping the appreciation of property in the area. 

After paying off the credit card debt I have from remodeling, realtors fees, and closing costs from the sale, I would have about $50k.My grandparents recently received $300k and a half acre lot in return for their investment in my dad's business.

Completely rehabbed and remodeled before we launched it as an Airbnb/STRThanks in advance! 

I've done roofs, heating systems, monitored fire alarm systems, unit remodels, etc. 

The home was built in the 50's and is in need of around 30k of remodeling to get rentable.
