You'll be fine, especially if you're using additional equity contribution to improve the property before your refinance.

The two additional units will be detached from the existing structure so there will be no interruptions from that standpoint.I have agreed to a temporary rent reduction at the tenant's request to compensate for the inconvenience and loss of the backyard during construction. 

Additionally, consulting with a financial advisor experienced in international real estate investments can provide further guidance tailored to your situation.I may also be able t find a lender besides a local bank!

This will help direct your search to the right areas, property types and price point.If you're purchasing all-cash, skip that step.Depending on your goal and preferred timeline for closing, the majority of your time should be spent searching for and analyzing deals.Searching: Look at public listing sites; connect with an investor friendly agent and choose 1 to work with who can search MLS and off-market inventory; for additional off-market options, consider growing your own database of wholesalers and homeowners Analyzing: Your agent can send comps and you can also search public listing sites for sold homes.

@George Goldstein, in addition to what others above have said.

3.Additional Fees: Are there other fees I should consider, such as maintenance coordination, lease renewal fees, or vacancy fees?

Just a few additional words of encouragement.

There is more to the formula on how much you can bring in, assuming you're self-employed.If you're an S-Corp, you can do the 23k as an employEE, then an additional 25% of your salary on top of that, with a maximum of $69k total. 

If you are buying a 2 unit building, especially if you are planning to buy additional investment real estate your best bet is to work directly with the smaller banks/credit unions in your community if that's where you are purchasing or in the area where you plan to buy.

Unexpected Costs: Real estate has a lot of additional costs that aren’t always obvious.
